Title: Localization and equivariant cohomology of real Grassmannians

Speaker: Chen He (Northeastern University)

Abstract: The rational cohomology of real and oriented Grassmannians was given in terms of Pontryagin classes and Euler classes by Leray (1949), Borel (1953) and Takeuchi (1962). In this talk we will consider certain torus actions on these Grassmannians and their rational equivariant cohomology using localization tools.
