Prairie Mathematics Colloquium: Ebrahim Samei

In this talk, we will first review the concept of inverse-closedness for a pair of algebras and its connection with an important property of groups known as being Hermitian (or symmetric). This property appears when one considers inverse-closedness for a particular pairs of algebras associated to a group G. After recalling and reviewing some known facts, we will aim to show how this concept relates to another important property of groups known as amenability. Our final goal is to give an affirmative answer to the long-standing conjecture that Hermitian groups are amenable. This solution is a based on a joint work with Matthew Wiersma (University of Winnipeg).

This event is part of the Prairie Mathematics Colloquium.
