Interval-closed set rowmotion and homomesy on products of two chains

Nadia Lafrenière, Joel Brewster Lewis, Erin McNicholas +2

We study rowmotion dynamics on interval-closed sets. Our first main result proves a simplification of the global definition of interval-closed set rowmotion from (Elder, Lafrenière…

Enumeration of interval-closed sets via Motzkin paths and quarter-plane walks

Sergi Elizalde, Nadia Lafrenière, Joel Brewster Lewis +3

We find a generating function for interval-closed sets of the product of two chains poset by constructing a bijection to certain bicolored Motzkin paths. We also find a functional…

Cyclic sieving on permutations -- an analysis of maps and statistics in the FindStat database

Ashleigh Adams, Jennifer Elder, Nadia Lafrenière +3

We perform a systematic study of permutation statistics and bijective maps on permutations using SageMath to search the FindStat combinatorial statistics database to identify appar…

Toggling, rowmotion, and homomesy on interval-closed sets

Jennifer Elder, Nadia Lafrenière, Erin McNicholas +2

Interval-closed sets of a poset are a natural superset of order ideals. We initiate the study of interval-closed sets of finite posets from enumerative and dynamical perspectives.…

Homomesies on permutations -- an analysis of maps and statistics in the FindStat database

Jennifer Elder, Nadia Lafrenière, Erin McNicholas +2

In this paper, we perform a systematic study of permutation statistics and bijective maps on permutations in which we identify and prove 122 instances of the homomesy phenomenon. H…

Approval Gap of Weighted k-Majority Tournaments

Jeremy Coste, Breenn Flesch, Joshua D. Laison +2

A -majority tournament on a finite set of vertices is defined by a set of linear orders on , with an edge in if in a majority of the linear…
