University of Toronto's Symplectic Geometry Seminar

Abstract: In this talk, I will give a Chevalley formula in equivariant K-theory. First, I will decompose the class of a line bundle in the equivariant K-theory of a Bott-Samelson variety. Then I will use this result to give a formula to multiply the class of a line bundle by the class of a Schubert variety in the equivariant K-theory of a flag variety
