THE DECREASE VALUE THEOREM WITH AN APPLICATION TO
PERMUTATION STATISTICS

**Abstract.**
The decrease value theorem is
restated and given a specialization more adapted to
Permutation Statistic Calculus. As an application, the
computation of a factorial several-variable generating
function for the wreath product of the cyclic group of
finite order by the symmetric group is given in full detail.
