Title: Twisted coproduct on the equivariant cohomology and its applications
Abstract:
We introduce the twisted coproduct structure on the equivariant cohomology of complete flag variety and discuss its various applications and generalizations (cohomology of a group, Peterson subalgebra, finite real reflection groups). This is based on recent joint projects with Martina Lanini, Rui Xiong and Changlong Zhong.
