Research Abstract

Some problems in Schubert calculus are studied from algebraic topological viewpoint. A type-uniform treatment for the torus equivariant cohomology ring of the flag varieties including exceptional ones is given. A generalisation of Schubert calculus to a class of manifolds with good Lie group actions is also obtained.
