Abstract

Using classical transformations on the symmetric group and two transformations constructed in Fix-Mahonian Calculus I, we show that several multivariable statistics are equidistributed either with the triplet (fix,@?des,@?maj), or the pair (fix,@?maj), where ''fix,'' ''des'' and ''maj'' denote the number of fixed points, the number of descents and the major index, respectively.
