The Leray-Hirsch Theorem for equivariant oriented cohomology of flag varieties
arXiv:2009.05902
Abstract
We use the formal affine Demazure algebra to construct an explicit Leray-Hirsch Theorem for torus equivariant oriented cohomology of flag varieties. We then generalize the Borel model of such theory to partial flag varieties.
