Quantum Algebra 2025-03-04 v2 Combinatorics

Abstract

We describe the embedding from the crystal of Kashiwara-Nakashima tableaux in type DD of an arbitrary shape into that of i\mathbf{i}-Lusztig data associated to a family of reduced expressions i\mathbf{i} which are compatible with the maximal Levi subalgebra of type AA. The embedding is described explicitly in terms of well-known combinatorics of type AA including the Sch\"{u}tzenberger's jeu de taquin and an analog of RSK algorithm.
