Pseudo-Permutations II: Geometry and Representation Theory

François Boulier, Florent Hivert, Daniel Krob, Jean-Christophe Novelli

Abstract


In this paper, we provide the second part of the study of the pseudo-permutations. We first derive a complete analysis of the pseudo-permutations, based on hyperplane arrangements, generalizing the usual way of translating the permutations. We then study the module of the pseudo-permutations over the symmetric group and provide the characteristics of this action.
