On the Eulerian Enumeration of Involutions

Abstract

We consider in this work the enumeration of involutions by descent sets, and based on that, by descent numbers. Formulas of the number of involutions with a prescribed descent set, with a prescribed descent number and Frobenius-type formulas are given.

Keywords

descent numbers, descent sets, Exact enumeration problems, generating functions, enumeration of involutions, Combinatorial inequalities, Frobenius type formulas
