Operator space theory from the maximal viewpoint
Gilles Pisier, Jean Roydor
We initiate a theory of ``operator spaces" (in other words subspaces of -algebras) with an emphasis on the maximal tensor product. The natural morphisms become the maximally b…
A non-commutative Amir-Cambern theorem for von Neumann algebras and nuclear -algebras
Eric Ricard, Jean Roydor
We prove that von Neumann algebras and separable nuclear -algebras are stable for the Banach-Mazur cb-distance. A technical step is to show that unital almost completely isome…
Dual operator algebras close to injective von Neumann algebras
Jean Roydor
We prove that if a non-selfadjoint dual operator algebra admitting a normal virtual diagonal and an injective von Neumann algebra are close enough for the Kadison-Kastler's metric,…
Near inclusions of amenable operator algebras
Jean Roydor
We prove that if an amenable operator algebra is nearly contained in a complemented dual operator algebra, then it can be embedded inside this dual operator algebra via a similarit…
Isomorphisms of tensor algebras of topological graphs
Kenneth R. Davidson, Jean Roydor
We show that if two tensor algebras of topological graphs are algebraically isomorphic, then the graphs are locally conjugate. Conversely, if the base space is at most one dimensio…
Subalgebras of and their modules
Jean Roydor
We give an operator space characterization of subalgebras of . We also describe injective subspaces of and then give applications to sub-TROs of . Fi…
