First semester Modules

MATH4A1 Techniques in Applied Mathematics 1   First Semester   10 points

This paper is an introduction to techniques for solving problems in applied mathematics. The focus of MATH4A1 will be on solving scalar equations. The topics will include techniques for ordinary differential equations, partial differential equations, difference equations, integral equations. We will discuss problems posed on continuum and discrete domains. We will also describe how mathematical models for real-world phenomena are derived.

MATH4AC Algebraic Combinatorics   First Semester   10 points

There is a rich interplay between abstract algebra and combinatorics. Algebraic combinatorics applies techniques from abstract algebra to combinatorial problems, or conversely applies combinatorial reasoning towards problems in algebra.

MATH4DG Differential Geometry   First Semester   10 points

Since the time of the ancient Greeks, mathematicians and philosophers have been interested in the geometry of curves and surfaces, for example the Euclidean plane and the surface of the earth. From the end of the 19th century onwards with the work of Riemann, however, a powerful mathematical theory of much more general classes of curved spaces arose; this is what is nowadays understood as differential geometry.

MATH4GR Introduction to General Relativity   First Semester   10 points

This module is an introduction to General Relativity, the theory of gravity by Albert Einstein. Building on the module Differential Geometry (MATH4DG), which takes place in the first half of semester 1, we develop Einstein’s idea that “space” and “time” form a continuum “spacetime” described by a 4-dimensional Lorentzian manifold.

MATH4HS Hilbert Spaces   First Semester   10 points

Corresponds to MATH301
This paper is an introduction to Hilbert spaces and linear operators on Hilbert spaces. It extends the techniques of linear algebra and real analysis to study problems of an intrinsically infinite-dimensional nature.

MATH4MA Modern Algebra   First Semester   10 points

Corresponds to MATH342
This paper introduces groups and rings. These are algebraic structures consisting of a set with one or more binary operations on that set satisfying certain conditions. These structures are ubiquitous throughout modern mathematics and this paper examines their properties and some applications.

MATH4MI Measure and Integration   First Semester   10 points

In school and in introductory courses in mathematics, integral usually means Riemann integral of a real-valued function on the real line. This fundamental concept reveals its beauty in the Fundamental Theorem of Calculus which relates integration and derivation. However, the Riemann integral has some shortfalls that make it inadequate for many purposes in modern analysis. One of them is a gap in the fundamental theorem of calculus: the class of Riemann integrable functions does not coincide with the class of all functions that have an antiderivative. Another drawback is that the interchange of point-wise limits of function sequences and their integrals is only possible under rather restrictive conditions.

In this paper we introduce a modern theory of integration via measure theory that overcomes these shortfalls. It goes back to the French mathematician Henri Léon Lebesgue (1875–1941) and is the gate to many exciting branches of mathematics, like, for instance, modern probability theory, functional analysis, or the theory of partial differential equations.

MATH4NM Numerical Methods   First Semester   10 points

Corresponds to COMO303
This paper develops the theory and techniques required to apply computational methods in modelling, applied mathematics and data analysis. Topics include matrix computation, data fitting, and the numerical solution of differential equations.

Second semester Modules

MATH4A2 Techniques in Applied Mathematics 2   Second Semester   10 points

This paper is an introduction to techniques for solving problems in applied mathematics. The focus of MATH4A2 will be on understanding the behavior of systems of equations. In many realistic applications, there are more than one dependent variables, and in this paper we will focus on techniques for studying systems of ordinary or partial differential equations. For systems of ordinary differential equations this will involve a study of dynamical systems and nonlinear dynamics, while we will also touch on chaos theory. Networks are becoming of increasing importance in applied mathematics, and we will outline some of the basic topics in network science, and then study dynamical systems which evolve over networks. We will also touch on the topic of stochastic differential equations. Returning to partial differential equations, we will discuss how to solve systems of partial differential equations. We will also describe how such systems may result in pattern formation, or even turbulence.

MATH4AA Asymptotic Analysis   Second Semester   10 points

Asymptotic analysis is a branch of mathematical analysis concerned with the limiting behavior of functions, in particular the behavior of functions when a variable or parameter is "large" or "small". The tools of asymptotic analysis are useful in describing the unknown solution to a number of algebraic, differential, or integral equations, particularly for those cases where solving such an equation exactly is not possible. One can, in such contexts, view the approach as yielding results which lie somewhere between exact solutions (which are nice, yet uncommon for many equations) and numerical simulations (which can be quite useful for understanding the behavior of a solution for a specific collection of parameters, but often less useful for deducing general behavior or structure). In a number of cases, an asymptotic approximation for a given function may even provide more insight than does the exact solution.

MATH4AR Advanced Topics in General Relativity   Second Semester   10 points

General relativity, Albert Einstein’s theory of gravitation, is one of the most elegant theories of mathematical physics. It gives a geometric description of gravitation in terms of the curvature of space and time, using mathematical methods like tensor algebra, differential geometry and the theory of ordinary and partial differential equations.

MATH4CA Complex Analysis   Second Semester   10 points

Corresponds to MATH302
This paper develops the differential and integral calculus of functions of a complex variable, and its applications.

MATH4DE Partial Differential Equations   Second Semester   10 points

Corresponds to MATH304
This paper gives an introduction to the theory of partial differential equations by discussing the main examples (Laplace's equation, Poisson's equation, transport equation, wave equation) and their applications.

MATH4FA Functional Analysis   Second Semester   10 points

The main focus of this course is the analysis of linear mappings between normed linear spaces. It turns out that many problems in analysis can be studied from this abstract point of view, which recognizes important underlying principles without getting lost in technical details. The applications of the approach ranges from differential and integral equations through problems in optimal control theory and numerical analysis to probability theory to name a few. This introductory course covers some of the basic constructions and principles of functional analysis: completions of metric/normed spaces, the Hahn-Banach Theorem and its consequences, dual spaces, bounded linear operators and their adjoints, closed operators, the Open Mapping and Closed Graph Theorems, the Principle of Uniform Boundedness and some elements of the spectral theory for closed linear operators. The applications of the abstract concepts are demonstrated through various examples from different branches of analysis.

MATH4GC Geometry of Curves and Surfaces   Second Semester   10 points

Corresponds to MATH306
This paper is an introduction to differential geometry; its focus is the structure of two-dimensional surfaces.

MATH4MD Mathematics of Data   Second Semester   10 points

A technical review of some of the most interesting and important aspects of theoretical statistics, machine learning, stochastic modelling and data analysis. The target audience is mathematics students. No prior background or appreciation of statistics required.

MATH4MP Mathematical Physics   Second Semester   10 points

Corresponds to MATH374
This paper presents the foundation theory for two major topics in Physics. The Classical Mechanics section introduces the formal framework of Classical Mechanics and illustrates its application to two-body problems, rotating systems, collisions, and chaos. The Special Relativity and Cosmology section covers the special theory of relativity with applications to relativistic mechanics, electrodynamics in covariant form, and cosmology. This paper is the same as the PHSI336 paper offered by the Physics Department. It is taught jointly by staff from both Departments.

MATH4OP Optimization   Second Semester   10 points

Optimization is a core tool of applied mathematics, computational modelling, statistics, operation research, finance, engineering, indeed almost any application of the mathematical sciences. This paper focuses on convex optimization, covering a few key algorithms, the theory behind them, and applications.

MATH4TO Topology   Second Semester   10 points

The subject of topology is rather abstract which means that it can be used in many different contexts. As a consequence it is fundamental for many branches in Mathematics. This paper is an introduction to point set topology. The notion of “closeness” is formalised and developed to define continuity of maps, connectedness of sets, convergence of sequences etc. There will be many familiar and unfamiliar examples to illustrate the power of this abstraction.
