Lexical tableaux and quasisymmetric functions

John M. Campbell, Spencer Daugherty

There is a natural bijection between standard immaculate tableaux of composition shape $α ⊨ n$ and length $ℓ (α) = k$ and the $ \left\{ \begin{smallmatrix} n \\ k \end{smallm…

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…

Ben Adenbaum, Spencer Daugherty, Nicholas Mayers

We establish a conjecture of Defant, Hopkins, Poznanović, and Propp concerning the dimensions of toggleability spaces for products of chains, shifted staircases, type-A root posets…
