On braided fusion categories - Semester 2, Session 23

This video is the recording of Session 23 (of Semester 2) of the course on braided fusion categories covering [DGNO10] in reference below. This session was given at the Beijing Institute of Mathematical Sciences and Applications (BIMSA) on 25/12/2025. Webpage: https://bimsa.net/activity/Onbrafusca...

Prerequisite Familiarity with the concept of fusion categories is assumed; however, key definitions and fundamental results will be reviewed. For further reading, please refer to [ENO05] and [EGNO15], as well as the videos and notes from the previous courses [I], [II], [III], [IV] and [B1] listed in the references. Introduction This course is a continuation of "On braided fusion categories" in [B1] and provides an in-depth exploration of the material presented in [DGNO10]. We begin with a comprehensive, self-contained overview of the key results on braided fusion categories, without assuming they are pre-modular or non-degenerate. The main focus of this course is to introduce the concept of the core of a braided fusion category, which allows us to identify the components of a braided fusion category that are not derived from finite groups. Even if you did not attend last semester, you are welcome to join this course, as it will start with a review of the material from the previous semester.
