Cocharacters of upper triangular matrices
Year: 2013 Journal: DOAJ (DOAJ: Directory of Open Access Journals)
Abstract
We survey some recent results on cocharacters of upper triangular matrices. In particular, we deal both with ordinary and graded cocharacter sequence; we list the principal combinatorial results; we show different techniques in order to solve similar problems.
