On braided fusion categories
This course closely examines the material in [DGNO10]. We begin by providing a thorough and self-contained overview of the known results on braided fusion categories, without assuming they are pre-modular or non-degenerate. Following this, the primary objective of this course is to introduce the concept of the core of a braided fusion category. This concept enables us to distinguish the components of a braided fusion category that are not derived from finite groups.

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], and [IV] listed in the references.
