Title:  A representation of B_n that restricts to the regular representation of B_{n-1}.

Abstract:   The n-th Lie representation is the multilinear component of the free Lie algebra on n generators. It is a representation of the symmetric group S_n with the remarkable property that its restriction to S_{n-1} is isomorphic to the regular representation. In this talk I will present a representation of the hyperoctohedral group with the same property. This representation arises as the top degree component of the so-called internal zonotopal algebra of the Gale dual of the type B reflection arrangement.
