Homomorphisms similar to completely contractive homomorphims

  • Wilson Pacheco Universidad del Zulia-Venezuela
Palabras clave: homomorphism, similarity, completely contractive

Resumen

Paulsen has proved that a unital homomorphism from an operator algebra contained in a C* - algebra is similar to a completely contractive homomorphism if and only if it is completely bounded. In the present note we obtain a different characterization when the operator algebra is separable.
