Canonical bases arising from $\imath$quantum covering groups

Quantum Algebra 2021-07-15 v1 Representation Theory

Abstract

For ı\imathquantum covering groups (U,Uı)(\mathbf{U}, \mathbf{U}^\imath) of super Kac-Moody type, we construct ı\imath-canonical bases for the highest weight integrable U\mathbf{U}-modules and their tensor products regarded as Uı\mathbf{U}^\imath-modules, as well as a canonical basis for the modified form of the ı\imathquantum group Uı\mathbf{U}^\imath, using the ıπ\imath^\pi-divided powers, rank one canonical basis for Uı\mathbf{U}^\imath.
