Classification of integral modular categories of Frobenius-Perron dimension pq^4 and p^2q^2 (1303.4748v1)
Published 19 Mar 2013 in math.QA and math.RT
Abstract: We classify integral modular categories of dimension pq4 and p2q2 where p and q are distinct primes. We show that such categories are always group-theoretical except for categories of dimension 4q2. In these cases there are well-known examples of non-group-theoretical categories, coming from centers of Tambara-Yamagami categories and quantum groups. We show that a non-group-theoretical integral modular category of dimension 4q2 is equivalent to either one of these well-known examples or is of dimension 36 and is twist-equivalent to fusion categories arising from a certain quantum group.
