Abstract

We study integral almost square-free modular categories; i.e., integral modular categories of Frobenius-Perron dimension pnmp^nm, where pp is a prime number, mm is a square-free natural number and gcd(p,m)=1{\rm gcd}(p,m)=1. We prove that if n5n\leq 5 or mm is prime with m<pm<p then they are group-theoretical. This generalizes several results in the literature and gives a partial answer to the question posed by the first author and H. Tucker. As an application, we prove that an integral modular category whose Frobenius-Perron dimensions is odd and less than 11251125 is group-theoretical.
