How to bounce your canon permutation

Danai Deligeorgaki, Krishna Menon

We study a new class of palindromic descent polynomials. Given a Dyck path $d$ of semilength $n$ and a permutation $I ¨ $ of size $n$ , one can label the up-steps and down-steps of $d…

Canon Permutation Posets

Matthias Beck, Danai Deligeorgaki

A permutation of the multiset ${1^{m}, 2^{m}, \dots, n^{m}}$ is a {\em canon permutation} if the subsequence formed by the $j$ th copy of each element of $[n] := {1, 2, \dots, n}$ is identica…

Ehrhart Bounds for Panhandle and Paving Matroids Through Enumeration of Chain Forests

Panhandle matroids are a specific family of lattice-path matroids corresponding to panhandle-shaped Ferrers diagrams. Their matroid polytopes are the subpolytopes carved from a hyp…
