Abstract:

The cohomology of Grassmannians and flag varieties has a rich structure which has been studied geometrically, algebraically, and combinatorially since the 19th century. It grew with the development of enumerative geometry, and influenced the development of intersection theory in algebraic geometry. Equivariant cohomology, which has been available for half a century, further enriches this structure and gives powerful new tools for studying it. These lectures will define and describe these equivariant cohomology rings, and discuss some of the recent developments.
