On the Descent Algebra of Type $D$

Combinatorics 2016-11-08 v1

Abstract

Here we give a combinatorial interpretation of Solomon's rule for multiplication in the descent algebra of Weyl groups of type DD, ΣDn\Sigma D_n. From here we show that ΣDn\Sigma D_n is a homomorphic image of the descent algebra of the hyperoctahedral group, ΣBn2\Sigma B_{n-2}.
