#### Spatial actions of Lévy groups (90 minute talk)

###### Pavlos Motakis (UIUC Math)

Abstract: Following up last week's seminar we prove a theorem of Glasner–Tsirelson–Weiss according to which any spacial action of a Lévy group is trivial.

4:00 pm in 447 Altgeld Hall,Wednesday, September 25, 2019

#### The renormalized De Rham functor

###### Ciaran O'Neill (Illinois Math)

Abstract: I’ll start with some background, then give the definition of the renormalized De Rham functor (as defined by Drinfeld and Gaitsgory). This comes with a natural transformation to the ordinary De Rham functor. I’ll mention how this can potentially be used to prove Kirwan surjectivity in certain circumstances. There will also be an example or two.

#### Tackling Gender Inequality in Math

###### Teryl Brewster (Office of Inclusion and Intercultural Relations)

Abstract: Professionals from the Office of Inclusion and Intercultural Relations will present a workshop focused on understanding the difference between sex and gender, how people face stereotypes because of the gender binary, and increasing awareness of where gender biases come from. The workshop will highlight these issues in the academic math context.
