Canonical bases arising from $$ quantum covering groups

Christopher Chung

For $$ quantum covering groups $(U, U^{})$ of super Kac-Moody type, we construct $$ -canonical bases for the highest weight integrable $U$ -…

Quantum supergroups VI. Roots of $1$

Christopher Chung, Thomas Sale, Weiqiang Wang

A quantum covering group is an algebra with parameters $q$ and $π$ subject to $π^{2} = 1$ and it admits an integral form; it specializes to the usual quantum group at $π = 1$ and to a qu…
