Structure and geometry of the tableaux algebra

Spencer Daugherty, Nicolle González, Bárbara Muniz +3

We study the monoid algebra $_{n} T_{m}$ of semistandard Young tableaux, which coincides with the Gelfand--Tsetlin semigroup ring $G T_{n}$ when $m = n$ . Among…

$c$ -Birkhoff polytopes

Esther Banaian, Sunita Chepuri, Emily Gunawan +1

In a 2018 paper, Davis and Sagan studied several pattern-avoiding polytopes. They found that a particular pattern-avoiding Birkhoff polytope had the same normalized volume as the o…

Type C $K$ -Stanley symmetric functions and Kraśkiewicz-Hecke insertion

Joshua Arroyo, Zachary Hamaker, Graham Hawkes +1

We study Type C $K$ -Stanley symmetric functions, which are $K$ -theoretic extensions of the Type C Stanley symmetric functions. They are indexed by signed permutations and can be us…

Hook-valued tableau uncrowding and tableau switching

Jihyeug Jang, Jang Soo Kim, Jianping Pan +2

Refined canonical stable Grothendieck polynomials were introduced by Hwang, Jang, Kim, Song, and Song. There exist two combinatorial models for these polynomials: one using hook-va…
