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.
Keywords:type $B$excedance; type $D$permutation; type $D$ derangement; fixed point; cycle
