Modular fusion categories with few twists

Quantum Algebra 2025-09-03 v1 Representation Theory

Abstract

We classify modular fusion categories up to braided equivalence with less than four distinct twists of simple objects by observing that under this assumption, for each positive integer NN, there are finitely many modular fusion categories of Frobenius-Schur exponent NN up to braided equivalence whose twists are a proper subset of the NthN^\mathrm{th} roots of unity.
