Plethysm Stability of Schur's $Q$-functions

Combinatorics 2026-03-17 v2 Quantum Algebra

Abstract

Schur functions has been shown to satisfy certain plethysm stability properties and recurrence relations. In this paper, use vertex operator methods to study analogous stability properties of Schur's QQ-functions. Although the two functions have similar stability properties, we find a special case where the plethysm of Schur's QQ-functions exhibits linear increase.
