Cluster Monomials are Dual Canonical

Quantum Algebra 2021-12-09 v1 Representation Theory

Abstract

Kang, Kashiwara, Kim and Oh have proved that cluster monomials lie in the dual canonical basis, under a symmetric type assumption. This involves constructing a monoidal categorification of a quantum cluster algebra using representations of KLR algebras. We use a folding technique to generalise their results to all Lie types.
