摘    要：Starting from a (small) rigid C*-tensor category with simple unit, we construct von Neumann algebras associated to each of its objects. These algebras are factors and can be either semifinite (of type II_1 or II_\infty , depending on whether the spectrum of the category is finite or infinite) or they can be of type III_{\lambda}, \lambda \in ( 0,1 ] . The choice of type is tuned by the choice of Tomita structure on certain bimodules we use in the construction. Moreover, we realize the whole tensor structure of the category directly by means of endomorphisms of these algebras, with finite Jones index.
