Summary: We define the notion of weakly ordered semigroups. For this class of semigroups, we compute the radical of the semigroup algebras. This generalizes some results on left regular bands and on 0- Hecke algebras.
Keywords: keywords weak order, left regular band, semigroup algebra, radical, Hecke algebra
