Title of Paper:On the descent polynomial of signed multipermutations

Journal:Proceedings of the American Mathematical Society

Summary:Motivated by a conjecture of Savage and Visontai about the equidistribution of the descent statistic on signed permutations of the multiset {1,1,2,2,...,n,n} and the ascent statistic on (1,4,3,8,...,2n-1,4n)-inversion sequences, we investigate the descent polynomials of the signed multipermutations.
