journal contribution
posted on 2023-05-16, 13:27 authored by Dascalescu, S, Kelarev, AV, van Wyk, LLet F be a field, and let A = Mn(F) be the algebra of all n × n matrices over F. For each finite semigroup S, we describe all gradings A = ⊕s∈SAs of A by S such that all standard matrix units eij of A are homogeneous elements of A.
