Abstract
In this article, the comodule structure of Chow rings of Flag manifolds is described by Schubert cells. Its equivariant version gives rise to a Hopf structure of the equivariant cohomology of flag manifolds . We get two identities of generalized Schubert polynomials as explanations of the geometric facts.
