Special Hardy Lecture

Friday 3rd July, 2015
BMA House, Tavistock Square, London (nearest tube: Euston)

The 150th Anniversary Hardy Lecturer is Professor Nalini Joshi (University of Sydney) who spoke at various venues across the UK during the month of June. Her 2015 Hardy Lecture Tour ended with a Special Hardy Lecture at the Society’s General Meeting at BMA House, London, on 3 July. The Society Meeting started at 3.30pm, and it was followed by the Special Hardy Lecture at 5.15pm.

Lecture 0. Symmetry through geometry

Abstract:

The search for symmetries of differential equations set in motion the development of extraordinarily important areas of mathematics. In this talk, we provide a new perspective on the corresponding problem for difference equations, by using a simple, beautiful geometric structure revealed in our recent study.  The objects of this study are partial difference equations that arise as discrete versions of famous PDEs. These discrete systems consist of equations fitted together in a self-consistent way on a square, a 3-cube or an N-dimensional cube. By using the beautiful geometric structure of space-filling polytopes, we show how to find their unexpected symmetry reductions.
