The signed Eulerian numbers on involutions
M. Barnabei, F. Bonetti, M. Silimbani
We define an analogue of signed Eulerian numbers for involutions of the symmetric group and derive some combinatorial properties of this sequence. In particular, we exhib…
Combinatorial properties of the numbers of tableaux of bounded height
M. Barnabei, F. Bonetti, M. Silimbani
We introduce an infinite family of lower triangular matrices , where counts the standard Young tableaux on cells and with at most columns on a suitable…
The Eulerian distribution on self evacuated involutions
Marilena Barnabei, Flavio Bonetti, Matteo Silimbani
We present an extensive study of the Eulerian distribution on the set of self evacuated involutions, namely, involutions corresponding to standard Young tableaux that are fixed und…
The descent statistic on involutions is not log-concave
Marilena Barnabei, Flavio Bonetti, Matteo Silimbani
We establish a combinatorial connection between the sequence counting the involutions on letters with descents and the sequence enumerating the semi…
