Ungar Games on the Young-Fibonacci and the Shifted Staircase Lattices

Yunseo Choi, Katelyn Gan

In 2023, Defant and Li introduced the Ungar move, which sends an element $v$ of a finite meet-semilattice $L$ to the meet of some subset of the elements covered by $v$ . More recent…

On the set partitions that require maximum sorts through the $aba -$ avoiding stack

Yunseo Choi, Katelyn Gan, Andrew Li +1

Recently, Xia introduced a deterministic variation $I ¨ _{I ¨} $ of Defant and Kravitz's stack-sorting maps for set partitions and showed that any set partition $p$ is sorted by $Ï^{N(p…
