Finite Semisimple Module 2-Categories

arXiv:2107.11037 · doi:10.1007/s00029-024-00998-4

Abstract

Let C be a multifusion 2-category. We show that every finite semisimple C-module 2-category is canonically enriched over C. Using this enrichment, we prove that every finite semisimple C-module 2-category is equivalent to the 2-category of modules over a rigid algebra in C.
