Seminar on Algebra, Geometry and Physics Modular categories (or non-degenerate braided fusion categories) can be thought of as
generalisations of quadratic spaces. All essential features of the theory of quadratic
spaces have analogues for modular categories. In particular it is possible to define Witt equivalence for modular categories. Witt classes form a group. This group is a convenient tool for classifying modular categories.
