Abstract
We give a description of the centralizer algebras for tensor powers of spin objects in the pre-modular categories (for odd) and (for even) in terms of quantum -tori, via non-standard deformations of . As a consequence we show that the corresponding braid group representations are Gaussian representations, the images of which are finite groups. This verifies special cases of a conjecture that braid group representations coming from weakly integral braided fusion categories have finite image.
