A counterexample to conjectures of Schlichting and of Antieau, Gepner and Heller

Abstract: 

After briefly recalling the basics of algebraic K-theory, we will recall the conjectures of Schlichting and of Antieau, Gepner and Heller. Some of you may remember the talk Gepner gave at the ANU last year, explaining the significance of the conjectures in the context of the partial results that were known at the time.

As it happens, both conjectures turn out to be false. A counterexample may be found in the preprint posted on the archive at https://arxiv.org/abs/2006.16536. In the talk I will sketch the main points.

Venue:

Seminar Room 1.33, Hanna Neumann Building 145 - for up to 25 people. All in person participants must register with Andrew Chew prior to the seminar.
