Coideal subalgebras of quantum $S L_{2}$ at roots of unity

Kenichi Shimizu, Rei Sugitani

We classify right coideal subalgebras of the finite-dimensional quotient of the quantized enveloping algebra $U_{q} (sl_{2})$ and that of the quantized coordinate algebra $\m…

Commutative algebras in Grothendieck-Verdier categories, rigidity, and vertex operator algebras

Thomas Creutzig, Robert McRae, Kenichi Shimizu +1

Let $A$ be a commutative algebra in a braided monoidal category $C$ ; e.g., $A$ could be an extension of a vertex operator algebra (VOA) $V$ in a category $C$ of…
