Abstract
We show that the core of a weakly group-theoretical braided fusion category is equivalent as a braided fusion category to a tensor product , where is a pointed weakly anisotropic braided fusion category, and or is an Ising braided category. In particular, if is integral, then its core is a pointed weakly anisotropic braided fusion category. As an application we give a characterization of the solvability of a weakly group-theoretical braided fusion category. We also prove that an integral modular category all of whose simple objects have Frobenius-Perron dimension at most 2 is necessarily group-theoretical.
