Title of Paper:The gamma-positivity of basic Eulerian polynomials

Journal:Journal of Combinatorial Theory, Series A

Abstract:We provide combinatorial interpretation for the gamma-coefficients of the basic Eulerian polynomials that enumerate permutations by excedance statistic and the major index as well as the corresponding gamma-coefficients for derangements.
