The module covers the basic manipulative skills in mathematics which are required by students studying a scientific discipline. The module begins with a review of arithmetic skills, before illustrating how algebraic expressions can be manipulated and rearranged. This includes exploration of fractions, powers, brackets, factors etc.

The concept of a function is introduced by investigating graphical techniques and then re-enforced by applying many of the algebraic methods introduced at the start of the module. The properties and graphs of a range of functions are analysed including polynomials, exponentials and trigonometric functions, with a range of examples explored.

The module begins by introducing some basic notation from set theory and how describing ‘sets’ or ‘events’ in this way can be used to define and calculate probabilities. This leads onto further investigation of some particular probability distributions (discrete and continuous) and their applications. Ways of exploring and illustrating data is also examined, before studying some statistical techniques that can be used to draw conclusions to observations or hypotheses.

The behaviour of fluid flows is important in a very wide variety of systems.  In weather and climate change studies it is necessary to predict and understand the general motion of both the air and the ocean. In medicine, it is important to know how blood flows in the arteries and the heart, and how air flows in the lungs. For instance, mathematically based simulations of the motion of blood in the heart have recently become sophisticated enough to guide surgeons when they take interventive action to treat various heart problems. In order to design aircraft it is necessary to know how wings can create a lifting force and how so-called viscous skin-friction can increase drag forces. If some means could be found to reduce skin-friction drag forces on aircraft by even just a few per cent, then this would translate into billions of pounds of savings in fuel costs for the airline industry every year.

The fundamental Euler and Navier-Stokes equations of fluid dynamics have been known for about two hundred and fifty years and a hundred and fifty years, respectively. Yet there remain many open and interesting questions about their solutions. This is despite the fact that, using a suitably compact notation, the equations are so short that they can each be written down in two lines.  The behaviour of turbulent flows, for example, can be described by solutions of these equations. Turbulent flows are ubiquitous in the natural world, as well as in engineered systems.  But no systematic means of obtaining turbulent solutions is known. Thus turbulence is an area of work that continues to attract the attention of many thousands of researchers, both in industry and over a range of academic departments within universities.

This module aims to provide students with a first look at the equations that govern the motion of fluids. We will extract a few simple solutions of these equations and discuss how they can be interpreted. To do this we will need to introduce various fundamental notions such as: particle paths; rates of change following the fluid flow (so-called material derivatives); mass and momentum conservation equations; and vorticity, which leads to an important distinction between two possible types of flow.

This introductory 10 credit year-three module uses elementary and combinatorial techniques to study how properties of divisibility can be used to characterise the integers. It also touches on some special numbers, such as Bernoulli and Euler numbers, and their corresponding polynomials. At the heart of the syllabus content is the topic of multiplicative arithmetic functions.

In number theory, an arithmetic, arithmetical, or number-theoretic function is a real or complex valued function f(n) defined on the set of natural numbers. We say that an arithmetic function which maps the natural numbers onto the complex plane, is multiplicative if f(mn) = f(m)f(n), for all natural numbers m and n with (m, n) = 1. If f(mn) = f(m)f(n) for all integers m and n, then we say that the function f is totally multiplicative.

In addition to multiplicative functions, this module contains sections on division in congruences, solving equations modulo a prime power, quadratic reciprocity, roots of unity, Dirichlet Series, Dirichlet Characters and Mobius inversion.

Knots are closed strings in three dimensional space. The fundamental question is to decide when two given knots are the same or if a particular knot is equivalent to another or even knotted at all. Knots have been studied by mathematicians for over a century but in the last 25 years a number of new simple ideas have contributed to remarkable breakthroughs which have helped clear up a large number of outstanding problems and conjectures. These ideas have come from a number of branches of mathematics and not only have influenced knot theory itself but have revolutionised several branches of mathematics and even mathematical physics. Applications have also been found in biology in understanding how DNA strands are knotted. This course is an elementary introduction to modern knot theory as it now stands and some of the tools which are now available for understanding knots. The style and emphasis is on using and understanding the tools rather than a traditional definition-theorem-proof approach.

The first part of the module aims to introduce students to first-order differential equations. Calculus techniques will be deployed to find simple solutions of such differential equations. In addition, students will be expected to develop an appreciation of how the solutions can be given a geometric interpretation, even when it is not possible to use calculus techniques to obtain solutions that can be written in a simple form.

The second part of the module is concerned with the solution of second-order differential equations. Manipulative techniques will be used to determine solutions of second-order differential equations for cases where the equation takes a specific and relatively simple form. There will also be some general discussion about the circumstances under which it is possible to know that there is a solution of a differential equation, even if a simple mathematical formula for the solution cannot be obtained.

In this module we will study rigorously real functions and their properties, focussing in particular on continuity and differentiability. We will give a mathematical definition of limits at a point, continuity, the derivative and the Riemann integral. We will show how to derive rigorously many of the computational rules already used at A-level.

Particular attention will be given to proving theorems for differentiable functions (as e.g. the Intermediate Value Theorem) and applications to maxima and minima, convexity and concavity. These tools can later be applied to qualitative study of functions and their graphs.

Later in the module we will introduce the Taylor expansion, which allows us to approximate most mathematical functions by polynomials. We will then study the general properties of the Riemann integral in detail, followed by the demonstration of the techniques of integration.

The module begins with the idea of a probability space, which is how we model the possible outcomes of a random experiment. Concepts such as statistical independence and conditional probability are introduced, and a number of practical problems are studied. We then turn our attention to random variables, and look at some well-known probability distributions. Following this we focus on discrete distributions, and introduce the idea of independence for random variables, and the important concept of mathematical expectation. This leads on to the study of random vectors, where we introduce covariance and correlation, conditional distributions and the law of total expectation. Finally, we show how the ideas developed for discrete distributions can be carried over to continuous distributions, and conclude with some approximation theorems.  

This is a lecture-based module. Students will be required to demonstrate problem-solving skills throughout the module. No previous knowledge of probability theory is assumed.

The module is intended to prepare students for subsequent modules involving probability and statistics within the degree scheme.

A lecture based module, providing an exposition of the basic theory and methods of complex analysis which are fundamental in mathematics and many of its applications.

The course shows how the concepts of differentiation and integration of real functions can be extended to complex functions. Complex functions map complex numbers to complex numbers. For a special subset of these functions it is possible to define a derivative. These differentiable complex functions have particularly nice properties. The real integral between two points x1 and x2 on the real axis is generalised to a complex integral along a path between two points z1 and z2 in the complex plane. These integrals are called contour integrals. Theorems of Cauchy show how some contour integrals of differentiable complex functions can be evaluated in a beautiful and simple way using methods known as the residue calculus. The residue calculus can be used to evaluate real integrals.

This course is essential for all mathematics students.

Matrix computation methods are introduced, and studied at length. The students are taught how to compute the kernel and the image of a linear map via matrices, and as an application — how to solve systems of homogeneous and non-homogeneous linear equations. Finally, we study how the matrix of a linear map changes with a change of basis and the standard form that it can be brought to.

This module will be dedicated to transferring all basic notions of calculus of functions of one variable to functions of several variables including limits, continuity, differentiation and integration. The second part of the module extends the calculus of several variables to the description and analysis of vector and scalar fields. There will be an emphasis on ideas and results that can be applied in many areas of mathematical modelling. But the main vector calculus theorems that will be presented are also of significance without regard to any such applications. This is because they can be viewed as being natural extensions – to cases involving more than one-dimension - of the fundamental theorem of calculus which relates the process of integration to that of anti-differentiation.

We use numbers in two different ways: the natural numbers 1, 2, 3... for counting; and the real numbers - fractions and decimals - for sizes, lengths, areas etc.

Number theory is about problems and methods where you just use the integers, meaning the extension of the natural numbers to include zero and negative numbers also:…-3, -2, -1, 0, 1, 2, 3…You can add, subtract and multiply integers, but you can't always divide exactly, so unless said otherwise, division means finding the quotient and remainder: m goes into n, q times with r left over, n = qm + r. If you fix m (the modulus) you can classify numbers according to the remainder r. This is called congruence or modulo arithmetic.

Addition and multiplication behave very differently in number theory. Given a number n, the equation x + y = n has lots of (integer) solutions, but xy = n has very few solutions, unless n = 0. If n is a prime number, the only solutions are x = 1, y = n or vice versa. The ancient Greeks knew, and proved, there are infinitely many prime numbers.

Number theory began with number puzzles. “Cattle problems" were ancient Babylonian and

Greek recreational maths puzzles - the Sudoku of their time. Now they are part of the number theory we meet in this module, with the name of Diophantine equations.

Number theory used to be the prize example of “useless" pure mathematics. Now, most of the security systems that protect our computers and bank accounts are built around disguising patterns by taking the remainders for some modulus m, and around the difficulty of factorising large numbers - i.e. solving xy = n with x; y > 1. E.g., even with a (simple) calculator it would take most humans quite a while to find that 4294967293 has just two prime factors. The numbers used in practical security are much bigger.

This part 1 introductory 10 credit second-year module contains sections on factorising integers, Euclid’s algorithm, congruence arithmetic, cattle problems, irrationality, and on continued fractions and quadratic equations.

A group consists of a set and a binary operation which satisfy certain axioms. Many important classes of mathematical objects can be regarded as groups, some examples being certain symmetry transformations or permutations under the operation of composition, integers under the operation of addition, nonzero rational numbers under the operation of multiplication, and invertible real square matrices of fixed size under the operation of matrix multiplication.

Some of the basic definitions and concepts in group theory were introduced in the Year One module MA1005 Foundations of Mathematics I.  This Year Two module will provide a reinforcement and extension of material from Year One, together with the introduction and study of further important definitions, theorems, proofs and examples.

Numerical Analysis is concerned with the development of numerical methods to solve mathematical problems in a reliable and efficient way. The ability to compute numerical solutions to mathematical problems has always been an important part of mathematics. For instance, an effective method for the evaluation of the square root of a number was discovered over 3600 years ago. Nowadays, numerical methods are under continuous research and development and are widely used in science, engineering, finance and other areas, to formulate theories, to interpret data, and to make predictions.

This module provides an introduction to computational methods for the approximation of functions on an interval of the real line. We begin with the study of methods and errors associated with the solution of systems of linear equations. We then study the interpolation of functions by polynomials of a given degree, and use these techniques for the derivation of numerical integration rules and their error analysis. In particular, we shall describe the use of orthogonal polynomials for the construction of polynomials of best approximation as well as their relevance in deriving Gauss-type numerical integration rules. We shall also turn our attention to interpolation by piecewise polynomials of low degree, known as splines. These are the building blocks for the construction of more advanced numerical methods, and require only minimal prerequisites in differential and integral calculus, differential equations, and linear algebra. Experience of numerical computation is essential for a true understanding of the applications and limitations of numerical methods, and numerous examples will be presented to explain and interpret the theoretical results.

The double module introduces students to some of the techniques of modern analysis which are indispensable tools to the present-day mathematician. The expansion of functions in Fourier series (if the function is defined on a bounded interval or periodic) or Fourier integrals is a very efficient method for solving a variety of problems in pure and applied mathematics – compared to power series expansion, it works under very weak assumptions on the regularity of the function. Indeed, even discontinuous functions can reasonably be expanded in a Fourier series, an observation which led to the modern definition of the concept of a function and to the development of mathematical analysis during the 19th and 20th centuries. The desire to give a satisfactory answer to the question which functions have a Fourier expansion, and in what sense, led to the abstract notions of normed vector spaces and Hilbert spaces, which have become the foundation of modern analysis and are used in all areas of mathematics. The fundamental idea is to try and extend the framework of linear algebra (matrix theory) to the study of more complicated linear operators, such as differential operators. This requires an infinite-dimensional setting, and ideas of analysis such as convergence and continuity become important. The aim of the course is to study Fourier series and integrals, with emphasis on conditions ensuring their pointwise, uniform or mean convergence, and to give an introduction to the more general theory of functional analysis, illustrated with some further applications.

This double module introduces the fundamentals of coding theory and data compression. 

The first part is devoted to coding theory and will mainly focus on error-correcting codes, their properties and applications. No document or computer files can be guaranteed free from error.  Error-correcting codes are used to spot mistakes and suggest the most likely correction. If the rate of errors is such that several mistakes are likely in a single ‘word’ (e.g. radio transmissions), then the codes used are more combinatoric.  If errors are so rare that having two mistakes in the same ‘word’ is very unlikely (e.g. brand new computer disc), then the codes used are more algebraic. Many error-correcting codes correspond to geometrical patterns.

The second part of the module deals with the broad field of data compression. We will first study lossless compression schemes, including the fundamental algorithms of Shannon, Huffman, Lempel-Ziv and arithmetic coding. Finally, the module will give the basic principles of lossy compression, such as quantization and transform coding. For instance, we will see the role wavelets (“the mathematical microscope”) play in data compression.

Topology is a subject of fundamental importance in many branches of modern mathematics.  Basically, it concerns properties of objects which remain unchanged under continuous deformation, which means by squeezing, stretching and twisting, but not cutting.  Apples and oranges are topologically the same, but you can’t deform an orange into a doughnut! More precisely, we can never deform in a continuous way a sphere (the surface of an orange) into a torus (the surface of a doughnut). Knots are also examples of topological objects, where a trefoil knot can never be deformed into an unknotted piece of string. It's the business of topology to describe more precisely such phenomena.

The aim of this module is to explore properties of topological spaces. To distinguish topological spaces we will consider topological invariants such as the fundamental group, which is a powerful way of using an algebraic invariant to detect topological features of spaces.

Partial differential equations are a central modelling tool in applied mathematics and mathematical physics. They also play an important role in pure mathematics, not least as a stimulus in the development of concepts and methods of classical and modern analysis.

This double module provides an introduction to the classical analytical treatment of second-order linear partial differential equations and techniques for their numerical solution. The essential concepts and methods are introduced and developed for prototype partial differential equations representing the three classes: parabolic; elliptic; hyperbolic. Finite difference and finite element approximations to the solutions of partial differential equations are developed. The accuracy and stability of the numerical schemes are investigated. Direct and iterative methods for solving the linear systems arising from the numerical approximation of partial differential equations are described.

The purpose of this double module is to consolidate students’ knowledge of and skills in modelling, analysis and applications. The module therefore is situated on the interface between Pure and Applied Mathematics and encompasses three important themes relevant to investigating physical phenomena, which will be addressed in series.

Theme 1. Asymptotic Methods

Many mathematical problems contain a small or large parameter that may be exploited to produce approximations to integrals and solutions of differential equations, for example. This theme provides an introduction to asymptotic approximations and perturbation analysis and their applications. Such techniques are important in almost every branch of applied mathematics especially those where exact analytic solutions are not available and numerical solutions are difficult to obtain.

Theme 2. Integral Equations

Many mathematical problems, particularly in applied mathematics, can be formulated in two distinct but related ways, namely as differential equations or integral equations. In the integral equation approach the boundary conditions are incorporated within the formulation of the problem and this confers a valuable advantage to the approach. The integral approach leads naturally to the solution of the problem in terms of an infinite series, known as the Neumann expansion. Integral equations have played a significant role in the history of mathematics. The Laplace and Fourier transforms are examples of integral equations. Another interesting problem is Huygens’ tautochrone problem, which is a special case of Abel’s integral equation. This course is concerned for the most part with linear integral equations. This module will introduce different types of integral equations and develop methods for their analysis and solution.

Theme 3. Calculus of Variations

What is the shortest distance between two points on a surface?  What is the shape of maximum area for a given perimeter?  These are two questions of the many that can be answered using calculus of variations.  The central problem involves an integral containing an unknown function – for example the length of a curve can be expressed as an integral along that curve.  Calculus of variations provides techniques for investigating minima of such integral functionals, which usually represent some physically or geometrically meaningful quantity. One example of great importance in modern technology is the use of minimisation in studying complex patterns observed under some conditions in shape-memory alloys. The course will consider the classical ``indirect'' approach to minimisation problems, through finding solutions of some related differential equations. However, due to some inherent (and indeed physically relevant) limitations of this method, which will become evident during the course, one has to combine it with a ``direct’’ variational technique. The power of the direct method spreads far and wide across the modern applications of mathematics. In particular, it provides a key to various techniques for finding approximate solutions to differential equations. 

This module can be taken by any student who is prepared to solve some differential equations and manipulate integrals.  Although some of the problems studied are of a physical origin, these will be presented in a self-contained way and there are no applied mathematics pre-requisites.

Regression analysis is arguably the most widely used in practice statistical tool. Fundamentals of regression analysis are thus the must for every student who will be seeking a statistics-related job. In a similar vein, the methods and principles of designing experiments are extremely important and regularly used by practitioners in a variety of disciplines. All the theoretical discussions are accompanied with solving practical problems.

This module will introduce the basics of multivariate statistical analysis to students.  The first few weeks the module deals with classic multivariate topics.  The last few weeks the module presents modern multivariate tools for classification and clustering and dimension reduction.  Throughout the semester the students will also use the lab to learn how to apply the techniques taught in class on large datasets using statistical software. 

The goal of the module is to help the students get a broad knowledge of how to handle multivariate problems.  The module is aimed to students with an OR/Stats degree who will likely encounter multivariate data in their careers as these become the norm in most real life problems.

This module examines the behaviours and properties of various algorithms that can be used for solving combinatorial operational research problems. Primarily the focus is on problems involving networks and graphs, though other sorts of problems such as packing and partitioning are also considered.

A number of problems are looked at, including graph connectivity, shortest path problems, spanning trees, maximum flow problems, matchings, routing problems, bin packing problems, and graph colouring problems. It is shown that some of these problems can be solved using efficient exact algorithms, while others require heuristic techniques and/or approximation algorithms. Hence key concepts surrounding intractability (NP-completeness) are also considered.

The module also considers a number of general purpose heuristic algorithms for intractable problems including metaheuristics. In particular, methods such as neighbourhood search, backtracking, simulated annealing, and evolutionary algorithms are considered.

This double module is an introduction to the mathematical foundations of optimisation and integer programming. In these topics one seeks to minimize or maximize a real function of real or integer valued variables, subject to constraints on the variables (equations or inequalities that need to be satisfied by all solutions). The main goals of the module are to describe the main mathematical properties of the optimisation problems, to introduce algorithms for finding optimal solutions and to show how these algorithms can be applied to a selection of classical optimisation problems.

In this module we explore techniques for modelling systems that exhibit uncertainty. Markov chains will be the principle tool, but we will also consider some important related processes such as renewal processes and diffusion processes.

Queueing theory is an important application of Markov chains, and this module will build on the material covered in MA0261. The module will also include numerous other applications, for example to problems such as insurance claims, epidemic growth, reliability, inventory management, and stock prices. Many of the exercises will involve simulation or require numerical solution methods, so it is recommended that students have some programming experience.

Recent tremendous technical advances in processing power, storage capacity, and inter-connectivity of computer technology are creating unprecedented quantities of digital data. Data mining (also known as Knowledge Discovery in Data, or KDD), the science of extracting useful knowledge from such huge data repositories, has emerged as a young and interdisciplinary field. Data mining techniques have been widely applied to problems in industry, science, engineering and government, and it is widely believed that data mining will have profound impact on our society.

This module provides an introduction to the basic ideas and methods of mathematical data mining. In this course, we will consider the following problems: classification, cluster and outlier analysis, mining time-series and sequence data, text mining and web mining, pattern analysis.

A lecture-based module open to all students with a suitable grounding. It covers the fundamental data mining ideas (clustering, support vector machine analysis, semi-supervised learning, information retrieval, collaborative filtering, harmonic analysis) and the most important algorithms (the k-means algorithm,  support vector machines,  PageRank algorithm, k-nearest neighbour classification, Naive Bayes).
