Research Seminar: The wonderful compactification and applications

Time: 14:15-16:00
Room: WSC-N-U-3.05

In the current semester, we will study the wonderful compactification and some of its applications. The most important example of wonderful compactification is a smooth projective compactification of a semi-simple linear algebraic group of adjoint type (e.g. $PGL_n$). We will study these compactifications from different points of view (and in a slightly more general setting), and in the last few talks of the seminar will look at an application, due to Bezrukavnikov and Kazhdan, to the representation theory of $p$-adic groups.
