# Colloquium: Tuesday, June 11, 2019. Speaker: Eli Bagno (Jerusalem College). Title: “On the poset of king-non-attacking permutations”.

Place: Room 614 in the Education & Sciences Building

Time: 14:00

Abstract:

A king-non-attacking permutation is a permutation $\pi \in S_n$ such that $|\pi(i)-\pi(i-1)|\neq 1$ for each $i \in \{2,\dots,n\}$.

We investigate the structure of the poset of these permutations under the containment relation,

and also provide some results on its Möbius function.

Tea will be served before the talk (at 13:50).
