Decreases and Descents in Words
Abstract.
The generating function for words by a
multivariable statistic involving decrease, increase, descent and
rise values is explicitly calculated by using the MacMahon Master Theorem
and the properties of the first fundamental transformation on words.
Applications to statistical study of the
symmetric group are also given.
