Similarities for the maximal tensor product of certain C*-algebras

Evangelos Papapetros

We prove that if the unital -algebras $\cl A$ and $\cl B$ satisfy Kadison's similarity property and the length $L=L\left(\cl A\tens\limits_{max}\cl B\right)$ of their maximal…

A new approach to the similarity problem

E. Papapetros

We say that a -algebra satisfies the similarity property ((SP)) if every bounded homomorphism , where $\mathit{H…

The similarity problem and hyperreflexivity of von Neumann algebras

G. K. Eleftherakis, E. Papapetros

The similarity problem is one of the most famous open problems in the theory of -algebras. We say that a -algebra $\cl A$ satisfies the similarity property ((SP) for shor…

Morita equivalence of w*-rigged modules

Evangelos Papapetros

The -rigged modules over dual operator algebras were introduced by Blecher and Kashyap as a generalization of -modules. In this paper, we introduce two new ty…

Hilbert modules, rigged modules and stable isomorphism

G. K. Eleftherakis, E. Papapetros

Rigged modules over an operator algebra are a generalization of Hilbert modules over a -algebra. We characterize the rigged modules over an operator algebra …

A Morita characterisation for algebras and spaces of operators on Hilbert spaces

G. K. Eleftherakis, E. Papapetros

We introduce the notion of and pairs for operator algebras and characterise pairs through their categories of left operator modules over these algebras. Furthermor…
