Morita equivalence for operator systems

George K. Eleftherakis, Evgenios T. A. Kakariadis, Ivan G. Todorov

We define $I^$ -equivalence for operator systems and show that it is identical to stable isomorphism. We define $I^$ -contexts and bihomomorphism contexts and show that two operator…

Hyperreflexivity of von Neumann algebras and similarity of finitely generated $C^{*}$ -algebras

G. K. Eleftherakis, V. I. Paulsen

Let $A$ be a $C^{*}$ -algebra. We say that $A$ satisfies the SP if every bounded homomorphism $A \to B (K)$ , with $K$ a Hilbert space, is similar to a $*$ -homomorphism. We introduce thr…

Symmetrisations of operator spaces

George K. Eleftherakis, Evgenios T. A. Kakariadis, Ivan G. Todorov

Let $A$ be a unital C*-algebra, $S$ be an operator $A$ -system and $E$ be an operator space that is a left operator $A$ -module. We introduce the symmetrisation of the pair $(E, S)$ a…
