A Collection of Problems on Spectrally Bounded Operators

Martin Mathieu

We discuss several open problems on spectrally bounded operators, some new, some old, adding in a few new insights.

The Maximal C*-Algebra of Quotients as an Operator Bimodule

Pere Ara, Martin Mathieu, Eduard Ortega

We establish a description of the maximal C*-algebra of quotients of a unital C*-algebra $A$ as a direct limit of spaces of completely bounded bimodule homomorphisms from certain o…

Maximal C-algebras of quotients and injective envelopes of C-algebras

Pere Ara, Martin Mathieu

A new C*-enlargement of a C*-algebra $A$ nested between the local multiplier algebra $M_{loc} (A)$ of $A$ and its injective envelope $I (A)$ is introduced. Various aspects of…

A not so simple local multiplier algebra

Pere Ara, Martin Mathieu

We construct an AF-algebra $A$ such that its local multiplier algebra $M_{loc} (A)$ does not agree with $M_{loc} (M_{loc} (A))$ , thus answering a question raised…
