This page will contain information relating to courses I am teaching, copies of the tutorial sheets and summaries of the material covered to date.

This course will extend the notions of continuity and limit for real valued functions which you have come across in Analysis 1A to **Rn**, to normed spaces and to metric spaces, and develop some topology in these spaces. We will also study sequences of functions and their relation with integration and power series.

MA30253: Continuum Mechanics

This course develops a general theory of continuum mechanics which can then be applied to modelling gases, fluids and elastic solids. In a continuum theory, we assume that the material is infinitely finely divisible, ignoring the atomic structure. This turns out to provide realistic models and predictions at length scales much larger than the interatomic distance. We then apply this theory to the study of inviscid fluids. (Unit description.)

In this course, we develop the general principles of the theory of elasticity. The classical theory of linear elasticity can then be obtained by expanding the constitutive law relating stress to strain in a neighbourhood of the undeformed state.

This course has the intertwoven themes of ordinary differential equations, the Calculus of Variations, Lagrangian Systems and Hamiltonian Systems, and looks at some of the elegant and striking connections between them.

Hamilton’s Principle states that a system evolves in such a way that a given integral over the path, called the action integral, is stationary. Fermat’s Principle, that light rays travel through a material along paths that minimise the total travel time, is an example of Hamilton’s Principle. The condition that the given integral is minimised then leads to a differential equation, called the Euler-Lagrange equation(s), for the path itself. This approach is known generally as a ‘variational principle’ and many familiar problems in physics, such as Newton’s laws of motion, can be recast in this way. The study of such variational problems constitutes the Calculus of Variations. In many cases, the Euler-Lagrange equations can in turn be recast as a first order autonomous system of differential equations, called a Hamiltonian System, which allows us to deduce general properties of solutions by studying the geometry of the flow induced by the differential equation(s) in the corresponding phase space.

The concepts and principles introduced in this course have led to many developments in modern pure mathematics (such as symplectic geometry and ergodic theory) and, besides applying to the equations of classical mechanics, they have motivated much of modern physics.
