This talk will discuss a new algebraic structure called triangulated persistence category (TPC). It combines the triangulated category structure with the persistence module structure. This algebraic structure can be used to associate a metric...

We will discuss p-local representation theory and conjectures of Broue and Alperin, the latter been inspired by finite groups of Lie type in characteristic p. The issue is the extent to which the category of representations can be reconstructed from...

Expander graphs are among the most useful objects in computer science and mathematics. They have found applications in numerous areas of both. I will review their definition, and explain some of the many applications. Time permitting, I will also...
