Stability Theorems for Forbidden Configurations
Richard P. Anstee, Benjamin Kreiswirth, Bowen Li +2
Stability is a well investigated concept in extremal combinatorics. The main idea is that if some object is close in size to an extremal object, then it retains the structure of th…

Cohomology of Pointed Finite Tensor Categories
Bowen Li, Gongxiang Liu
We consider the finite generation property for cohomology algebra of pointed finite tensor categories via de-equivariantization and exact sequence of finite tensor categories. As a…

On Gauge Equivalence of Twisted Quantum Doubles
Bowen Li, Gongxiang Liu
We study the quantum double of a finite abelian group twisted by a -cocycle and give a sufficient condition when such a twisted quantum double will be gauge equivalent to a…
