    Combinatorics for Graded Cartan Matrices of the Iwahori-Hecke Algebra of Type A

    Combinatorics concerning graded Cartan matrices for the Iwahori-Hecke algebra of type A is investigated. We give several descriptions for the determinant of the graded Cartan matrix, which imply some combinatoria...
