Vicky Neale

It is with huge sadness and a profound sense of loss that we must announce that Vicky Neale, teacher, advocate, inspiration and much loved colleague, died on May 3 after a long illness.

Vicky is well known to many people in the mathematical community and beyond, from fellow academics to the many schools that she visited and, most of all, through her many lectures, talks and films. Her digital footprint is a fitting and wonderful legacy.

Diffusion Limited Aggregation: what we do and do not know about it

Dmitry Belyaev
Abstract

Diffusion Limited Aggregation is a very simple mathematical model which describes a wide range of natural phenomena. Despite its simplicity, there is very little progress in understanding its large-scale structure. Since its introduction by Witten and Sander over 40 years ago, there was only one mathematical result. In 1987 Kesten obtained an upper bound on the growth rate. In this talk I will discuss DLA and some related models and the recent progress in understanding DLA. In particular, a new simpler proof of Kesten result which generalizes to other aggregation models.
