Abstract

We will introduce the notion of strong Morita equivalence for completely positive linear maps and study its basic properties. Also, we will discuss the relation between strong Morita equivalence for bounded CC^*-bimodule linear maps and strong Morita equivalence for completely positive linear maps. Furthermore, we will show that if two unital CC^*-algebras are strongly Morita equivalent, then there is a 111-1 correspondence between the two sets of all strong Morita equivalence classes of completely positive linear maps on the two unital CC^*-algebras and we will show that the corresponding two classes of the completely positive linear maps are also strongly Morita equivalent.
