Title: Topological Order, Tensor Networks and Subfactors

Abstract: We present recent progress on studies of 2-dimensional topological order in terms of tensor networks and its connections to subfactor theory. We explain how Drinfel'd centers and higher relative commutants naturally appear in this context and use of picture language in this study.
