Contractions and applications of crystal skeletons: Young quasisymmetric and Stanley symmetric functions
Sarah Brauner, Zajj Daugherty, Sarah Mason +1
The paper studies how crystal skeletons of slₙ‑crystals can be further decomposed into quasicrystal skeletons whose characters are Young quasisymmetric Schur functions, and shows h…

A new proof of an EÄecioÄlu--Remmel inverse Kostka matrix problem via a Garsia--Milne involution involving Sym and NSym
Edward E. Allen, Kyle Celano, Sarah K. Mason
EÄecioÄlu and Remmel provide a combinatorial proof (using special rim hook tableaux) that the product of the Kostka matrix and its inverse equals the identity matrix…
