摘要
Let e be a fusion category which is an extension of a fusion category D by a finite group G. We classify module categories over e in terms of module categories over XI and the extension data (c, M, alpha) of C. We also describe functor categories over e (and in particular the dual categories of C). We use this in order to classify module categories over the Tambara Yamagami fusion categories, and their duals.
