| Popis: | We prove that braided fusion categories of Frobenius-Perron $p^mq^nd$ or $p^2q^2r^2$ are weakly group-theoretical, where $p,q,r$ are distinct prime numbers, $d$ is a square-free natural number such that $(pq,d)=1$. As an application, we obtain that weakly integral braided fusion categories of Frobenius-Perron dimension less than $1800$ are weakly group-theoretical, and weakly integral braided fusion categories of odd dimension less than $33075$ are solvable. For the general case, we prove that fusion categories (not necessarily braided) of Frobenius-Perron dimension $84$ and $90$ either solvable or group-theoretical. Together with the results in the literature, this shows that every weakly integral fusion category of Frobenius-Perron dimension less than $120$ is either solvable or group-theoretical. Thus we complete the classification of all these fusion categories in terms of Morita equivalence. Comment: The whole paper is updated and contents are extended |
