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, $τ = 123$ and $n$ …

The distribution of consecutive patterns of length 3 in $3 - 1 - 2$ -avoiding permutations

M. Barnabei, F. Bonetti, M. Silimbani

We exploit Krattenthaler's bijection between the set $S_{n} (3 - 1 - 2)$ of permutations in $S_{n}$ avoiding the classical pattern $3 - 1 - 2$ and Dyck $n$ -p…
