Title: Y-proper Graded Cocharacters Of Upper Triangular Matrices Of Order M Graded By The M-tuple ϕ=(0, 0, 1,..., M-2)
Author: Centrone L.
Cirrito A.
Abstract: Let F be a field of characteristic 0. We consider the algebra UTm(F) of upper triangular matrices of order m endowed with an elementary Zm-grading induced by the m-tuple ϕ=(0, 0, 1,..., m-2), then we compute its Y-proper graded cocharacter sequence and we give the explicit formulas for the multiplicities in the case m=2, 3, 4, 5.
