Interval Posets and Polygon Dissections
Eli Bagno, Estrella Eisenberg, Shulamit Reches +1
The Interval poset of a permutation is an effective way of capturing all the intervals of the permutation and the inclusions between them and was introduced recently by Tenner. Thi…
Blockwise simple permutations
Eli Bagno, Estrella Eisenberg, Shulamit Reches +1
A permutation is called {\it {block-wise simple}} if it contains no interval of the form or . We present this new set of permutations and explore s…
Counting King Permutations on the Cylinder
Eli Bagno, Estrella Eisenberg, Shulamit Reches +1
We call a permutation a {\em cylindrical king permutation} if for each and . We present some results…
Separators - a new statistic for permutations
Eli Bagno, Estrella Eisenberg, Shulamit Reches +1
A digit in a permutation is defined to be a separator of if by omitting it from we get a new block. In this work we introduce a new st…
On the poset of King-Non-Attacking permutations
Eli Bagno, Estrella Eisenberg, Shulamit Reches +1
A king-non-attacking permutation is a permutation such that for each . We investigate the structure of the poset of these perm…
On two-sided gamma-positivity for simple permutations
Ron M. Adin, Eli Bagno, Estrella Eisenberg +2
Gessel conjectured that the two-sided Eulerian polynomial, recording the common distribution of the descent number of a permutation and that of its inverse, has non-negative intege…
