Geometry of Flag Varieties

Abstract.  Flag varieties are homogeneous manifolds G/B, where G is a  
connected algebraic group and B a Borel subgroup. For instance, one  
can take G to be the group of invertible nxn matrices and B its  
subgroup of invertible upper triangular matrices. Most of the geometry  
of flag varieties is encoded in the combinatorics of the Weyl group.  
In the previous example, the Weyl group corresponds to the symmetric  
group on n letters. Flag varieties also have nice cellular  
decompositions and their topology can be understood via Schubert  
calculus and operators of divided differences. In this introductory  
talk, I will give an overview of the subject and explain how the  
geometry of flag varieties provides a powerful insight into the study  
of singular algebraic varieties.
