| 释义 |
In category theory, a branch of mathematics, a spherical category is a pivotal category (a monoidal category with traces) in which left and right traces coincide.[1] Spherical fusion categories give rise to a family of three-dimensional topological state sum models (a particular formulation of a topological quantum field theory), the Turaev-Viro model, or rather Turaev-Viro-Barrett-Westbury model.[2] References1. ^{{cite journal|journal=Advances in Mathematics|volume=143|issue=2|pages=357–375|year=1999|title=Spherical Categories|authors=John W.
