Tensor categories arise naturally from subfactors, quantum groups and many other mathematical objects. In particular, the classification of subfactors is closely related to actions of tensor categories on a factor. We use this machinery to C*-algebras and overview a possible direction toward classifying C*-subalgebras of finite index.
