The signed Eulerian numbers on involutions.
[Preprint]

Abstract
We define an analogue of signed Eulerian numbers fn;k for involutions
of the symmetric group and derive some combinatorial properties
of this sequence. In particular, we exhibit both an explicit formula and a
recurrence for fn;k arising from the properties of its generating function.
