Excedance Numbers for Permutations in Complex Reflection Groups

Abstract. Recently, Bagno, Garber and Mansour [Sém. Lotharingien Combin. 56 (2007), Art. B56d] studied a kind of excedance number on the complex reflection groups and computed its multidistribution with the number of fixed points on the set of involutions in these groups. In this note, we consider the similar problems in more general cases and make a correction of one result obtained by them.
