G_2-Laplacian Flow
Serge is probably best known outside France for 'Je t'aime', but he was responsible for many other and better works across various media including film and prose and especially via 16 albums.
This track is from 1968. It is based on an English language poem written by 'Bonnie' Parker, one half of the 1930s outlaw couple after whom the song is named. Brigitte shares the vocals with Serge.

On the Balog-Szemerédi-Gowers theorem
Abstract
The Balog-Szemerédi-Gowers theorem is a powerful tool in additive combinatorics, that allows one to roughly convert any “large energy” estimate into a “small sumset” estimate. This has found applications in a lot of results in additive combinatorics and other areas. In this talk, we will provide a friendly introduction and overview of this result, and then discuss some proof ideas. No hardcore additive combinatorics pre-requisites will be assumed.

Signatures of Streams - Professor Terry Lyons
A calculator processes numbers without caring that these numbers refer to items in our shopping, or the calculations involved in designing an airplane. Number without context is a remarkable abstraction that we learn as infants and which has profoundly affected our world.
Our lives start, progress in complex ways, and are finally complete. So do tasks executed on a computer. Multimodal streams are a pervasive “type”, and even without fixing the context, have a rich structure. Developing this structure leads to wide-ranging tools that have had award-winning impact on methodology in health care, finance, and computer technology.
Terry Lyons is Professor of Mathematics in Oxford and a Fellow of St Anne's College. His research is supported through the DataSig and Cimda-Oxford programmes.
