Hyperreflexivity of von Neumann algebras and similarity of finitely generated -algebras
G. K. Eleftherakis, V. I. Paulsen
Let be a -algebra. We say that satisfies the SP if every bounded homomorphism , with 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 be a unital C*-algebra, be an operator -system and be an operator space that is a left operator -module. We introduce the symmetrisation of the pair a…
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…
Homomorphisms of algebras and Fourier algebras
M. Anoussis, G. K. Eleftherakis, A. Katavolos
We investigate conditions for the extendibility of continuous algebra homomorphisms from the Fourier algebra of a locally compact group to the Fourier-Stieltjes alge…
Synthetic properties of locally compact groups: preservation and transference
M. Anoussis, G. K. Eleftherakis, A. Katavolos
Using techniques from TRO equivalence of masa bimodules we prove various transference results: We show that when is a group homomorphism which pushes forward the Haar measure o…
Idempotents of large norm and homomorphisms of Fourier algebras
M. Anoussis, G. K. Eleftherakis, A. Katavolos
We provide necessary and sufficient conditions for the existence of idempotents of arbitrarily large norms in the Fourier algebra A(G) and the Fourier-Stieltjes algebra B(G) of a l…
