Lyndon bases of split $\imath$quantum groups

Quantum Algebra 2025-11-18 v2 Representation Theory

Abstract

We introduce and study Lyndon bases of split ı\imathquantum groups Uı(g)\mathbf{U}^\imath(\mathfrak{g}). A relationship between the Lyndon bases and PBW-type bases was provided. As an application, we establish the existence of canonical bases for the type A split ı\imathquantum groups Uı(sln)\mathbf{U}^\imath(\mathfrak{sl}_n).
