摘要
If is a subset of the set of reflections of a finite Coxeter group , we define a sub--module of the group algebra . We provide examples where this submodule is a subalgebra. This family of subalgebras includes strictly the Solomon descent algebra and, if if of type , the Mantaci-Reutenauer algebra.
