From Unit Interval Orders to Totally Nonnegative Matrices: Permanental Inequalities and Bruhat-Increasing Bijections

Sihong Pan, Mark Skandera, Jiayuan Wang

Given an $n \times n$ matrix $A = (a_{i, j})$ and subsets $I, J$ of $[1, n] := {1, \dots, n}$ , let $A_{I, J} = (a_{i, j})_{i \in I, j \in J}$ denote the $(I, J)$ -submatrix of $A$ . We prove that,…

Permanental Inequalities and Unit Interval Orders

Sihong Pan, Mark Skandera, Jiayuan Wang

Given a square matrix, the permanent is a determinant-like function without signs. In this paper, we study inequalities involving permanents of certain submatrices. We first focus…

On Kazhdan--Lusztig basis elements having no reversal factorization

Tommy Parisi, Ben Spahiu, Mark Skandera +1

For $w$ in the symmetric group $S_{n}$ , let $C_{w}$ be the corresponding modified, signless Kazhdan--Lusztig basis element of the type- $A$ Hecke algebra $H_{n} (q)$ . An extensi…
