What is Schubert Operators in Kac-Moody Theory about?
This document summarizes formulas for the structure constants of multiplication of equivariant Schubert classes in equivariant cohomology and K-theory of flag manifolds. The authors introduce new operators whose coefficients compute these structure constants, generalizing previous positive formulas. They prove their formulas using Bott-Samelson manifolds and the (K-)cohomology basis dual to the (K-)homology basis of sub-Bott-Samelson manifolds.
