The Eulerian numbers on restricted centrosymmetric permutations
Marilena Barnabei, Flavio Bonetti, Matteo Silimbani
We study the descent distribution over the set of centrosymmetric permutations that avoid the pattern of length 3. Our main tool in the most puzzling case, namely, and …

The descent statistic over 123-avoiding permutations
M. Barnabei, F. Bonetti, M. Silimbani
We exploit Krattenthaler's bijection between 123-avoiding permutations and Dyck paths to determine the Eulerian distribution over the set of 123-avoiding permutations in…
