Excedance Numbers for Permutations of Type $D$
首发时间:2014-12-01
Abstract:This work provides a study on the multidistribution of type $B$excedances, fixed points and cycles on the permutations of type$D$. We derive the recurrences and closed formulas for thedistribution of signed excedances on type $D$ permutations as wellas derangements via combinatorial construction.
