Operator space tensor products and Hopf convolution algebras

Edward G. Effros, Zhong-Jin Ruan

Research output: Contribution to journalArticlepeer-review


It is shown how one may use operator space tensor product to define Hopf algebraic operations on the preduals of Hopf von Neumann algebras. A careful discussion of the extended Haagerup tensor product is presented which includes a useful technique for handling computations with products of infinite matrices.
