Weighted lattice point enumeration in lecture hall order polytopes
Katharina Jochemko, Krishna Menon
We consider weighted lattice point enumeration in lecture hall order polytopes. We observe that these half-open polytopes are closed under weight-lifting for a large class of polyn…
Gamma-positivity for octopuses: a bijective proof
Krishna Menon
Chapoton introduced an interesting family of polytopes called arbor polytopes, where a polytope is associated to any arbor . Chapoton conjectured that the polyno…
Ehrhart positivity for marked order polytopes
Katharina Jochemko, Krishna Menon
Given a pair of finite posets , the function counting integer-valued order preserving extensions of an order preserving map from to…
How to bounce your canon permutation
Danai Deligeorgaki, Krishna Menon
We study a new class of palindromic descent polynomials. Given a Dyck path of semilength and a permutation of size , one can label the up-steps and down-steps of …
Descent-restricted subsequences via RSK and evacuation
Krishna Menon, Anurag Singh
The length of a longest increasing subsequence in a permutation has been extensively studied. An increasing subsequence is one that has no descents. We study g…
