Morita invariants of quasitriangular coideal subalgebras
Monique Müller, Chelsea Walton
We use representations of braid groups of Coxeter types BC and D to produce invariants of representation categories of quasitriangular coideal subalgebras. Such categories form a p…

Twists of graded algebras in monoidal categories
Fernando Liu Lopez, Chelsea Walton
Zhang twists are a common tool for deforming graded algebras over a field in a way that preserves important ring-theoretic properties. We generalize Zhang twists to the setting of…
