Abstract: 
Perverse sheave have important applications to representation theory, number theory, and algebraic geometry. I will discuss work in progress to understand the category of perverse sheaves on the Baily-Borel compactification of a Hermitian locally symmetric space; the method is to first work on the less singular reductive Borel-Serre compactification and then push down. Along the way I will introduce these various compactifications and give examples.
