This paper proves the property F conjecture for a large class of MTCs. Namely, M-Metaplectic categories for odd N.

What is interesting about this paper is that it highlights one property which makes weakly integral fusion categories special: it is a Galois invariant property, and hence modularity is respected to some extent by Galois action. One of the key difficulties in proving property F comes in answering the question "what makes weak integrality so special, anyways?" so this might approximate an answer.
