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
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.

Symmetry through Geometry
6.30 Reception at De Morgan House
7.30 Society Dinner
These lectures were aimed at a general mathematical audience. All interested, whether LMS members or not, were most welcome to attend this event.
The Society Dinner was held at the Blue Door Bistro, Montague on the Garden Hotel, Montague Street. The cost to attend the Society Dinner was £35.00 per person (inclusive of wine).
The Society Meeting was immediately preceded by a Graduate Student Meeting, which also took place at BMA House, Tavistock Square, at 10.00.
