APMA 900 • Asymptotic Analysis of Differential Equations

Exact & Approximate Methods for Understanding DEs One aim of this course is to provide an introduction to exact methods for the solution of ordinary and partial differential equations (ODEs & PDEs). Fourier series methods for solving linear DEs are extended to integral solution methods that include the Fourier and Laplace transforms. Investigation of this solution perspective establishes the close connection between complex variable theory and DEs. A different generalization of the Fourier idea leads to the development of Sturm-Liouville eigenfunctions, function (Hilbert) spaces and special function theory. But many ODEs and PDEs encountered in applications are not amenable to exact solution, particularly those involving nonlinearity. Another aim is to introduce a variety of approximation methods that extend our analytical toolbox beyond exact theory. Nonlinear ODEs systems provide many example contexts for the development of these powerful tools. The results can also be useful in benchmarking numericallycomputed solutions, and even decoding exact solutions whose formula complexity defies interpretation. Perturbation theory analyzes problems that are “nearby” to those with known exact properties. This perspective also gives mathematical insight into the consequences of approximations that neglect complicating effects in the reduction of model equations. Finally, yet other types of asymptotic methods address singular situations where small changes to DE problems have a large impact on their solution. Lectures will be based upon a case-study approach of ODE & PDE examples that draw from the interests of course participants. Computational graphics will be an important tool for the lectures and assigned work. Visualization and numerical computing will involve the use and modification of Python & Matlab scripts.

APMA 990 - Mathematics of Evolution

Much of our understanding of evolution, the process shaping the beautiful biological diversity in our world, is grounded in equally elegant mathematics. In this course we will cover the mathematical description of evolution. Involving a wide range of topics, from the analysis of non-linear dynamics to stochastic processes and partial differential equations, this course will challenge you to take mathematical principals and apply them to the natural world. Throughout this course we will focus particularly on addressing important contemporary existential questions with mathematical models, for example applications of evolution to conservation and public health.

MATH 495/795 - Differential Geometry: Curves – Surfaces – Manifolds

Differential geometry is a core subject in mathematics. The tools of differential geometry are routinely used in most subfields of mathematics, while at the same time they have wide applications in various theoretical as well as applied disciplines such as physics (theory of relativity, mechanics), econometrics, computer graphics, signal processing and statistics.

The course is a mathematically rigorous introduction to the fundamental notions in differential geometry: curves, surfaces and abstract differentiable manifolds. About half of the course focuses on curves and surfaces in three-dimensional Euclidean space and introduces key concepts such as first and second fundamental forms, Gauss curvature, covariant derivative and geodesics. The second part of the course centres on Riemannian manifolds, and presents important concepts such as Riemannian connection and the curvature tensor. Towards the very end of the class we will discuss about the General Theory of Relativity, a remarkable application of differential geometry

MATH 708 - Discrete Optimization - Surrey Campus

Discrete optimization is a field that has grown almost from scratch in the past 70 years. This development is driven in part from its applicability to a wide range of practical problems, such as scheduling and network design, and its close ties to computer science.

MATH 795 - G100 Introduction to Topology

Some of us like coffee. Some of us like donuts. In what sense is a coffee cup similar to a donut? Such a question deals with mathematics in field of topology.

MATH 800 - G200 Optimal Transportation - remote

The goal of this course is to teach the students to use mathematical models to improve and optimize public transport networks.

There will be two or three guest lecturers for this course Professor Robert Shorten from Imperial College London, Dr Emanuele Crisostomi from University of Pizza, and/or Professor Tarek Sayed from University of British Columbia.

MATH 716 - Numerical Analysis II

Differential Equations (DEs) are the building blocks for mathematical models of physical processes found throughout science and engineering. Since the vast majority of DEs cannot be solved exactly, it is vital to develop algorithms to compute approximate solutions. Suffice to say, many of the things we take for granted in the modern world rely critically on the fast, accurate and robust solution of DEs.

How many beds do hospitals need to reduce emergency department overcrowding? How many COVID-19 cases will there be in the fall? How can airlines optimize their routes?

Galois theory studies roots of polynomial equations, combining field theory and group theory to study symmetries of these equations. Famously, these ideas led to a proof that (unlike the quadratic formula for degree-2 polynomials) no formula exists to solve polynomial equations of degree 5 or more. Proving this theorem is one goal of this class.
