| Research Abstract |
We have studied the representation theory of Hecke algebras, certain finite dimensional algebras which play important roles in Lie theory. Fock spaces originally appeared in mathematical physics and the categorification of the Fock spaces is an active field of research in recent days. We have also obtained several results which contribute to the development. The results obtained in the research include, identification of geometric and algebraic constructions of irreducible modules over the affine Hecke algebra of type A, theory to compute graded decomposition numbers of a graded quantized Schur algebra via categorification of the deformed Fock space, etc.
