Cohomology of Pointed Finite Tensor Categories (2410.09549v1)
Published 12 Oct 2024 in math.QA and math.RT
Abstract: 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 result, we prove that all coradically graded pointed finite tensor categories over abelian groups have finitely generated cohomology.
