Time: Wednesday, 11.03.2026, 14:00.

Abstract: I will discuss some surprising implications between the complexity of hyperfiniteness and the existence of certain types of equivalence relations, in particular, establishing formal implications between well-known open problems of the topic. Based on joint work with Josh Frisch and Forte Shinko.
