The purpose of the ART seminar is to present topics that are related to Mathematical Topology, but in a more applied context (e.g. Probability, Combinatorics, Statistics, Engineering). ART started only in 2016, but is the culmination of 4-5 years of earlier, less formal, seminar series in various aspects of Applied and Random Topology.
The SPSP seminar covers all topics in Pure and Applied Probability and Stochastic Processes. It started in 1980, and so in 2015 we celebrated its 35th anniversary (along with a couple of birthday parties).
