Abstract

 

The wonderful compactification X of a semisimple adjoint group G was introduced by De Concini and Procesi. It stands out as the role model for understanding other group embeddings. It also serves as a model for us to understand the bahavior at infinity of some group theoretical constructions in G.

In this talk, we will discuss some recent results on the wonderful compactifications. If time allows, we will also mention some results on the complete symmetric varieties.
