DESCRIPTION:Speakers: Andrew Snowden (Michigan)\n\nPre-Tannakian tensor ca
 tegories are a natural generalization of representation categories of alge
 braic groups. I will define a subclass of these categories (the "discrete"
  ones) that correspond to finite groups. This idea leads one to a construc
 tion of pre-Tannakian categories based on certain infinite permutation gro
 ups\, called oligomorphic groups\, equipped with some numerical data. I wi
 ll explain this\, and some of the novel examples it yields. (Joint with Na
 te Harman.)\n\nhttps://math-events.uni-bonn.de/event/476/
