(Non-)amenability of the Fourier algebra in the cb-multiplier norm

Volker Runde

For a locally compact group $G$ , let $A (G)$ denote its Fourier algebra, $M_{c b} (A (G))$ the completely bounded multipliers of $A (G)$ , and $A_{M_{c} b} (G)$ the closure of $A (G)$ in $M_{…

Operator ultra-amenability

Brian E. Forrest, Volker Runde, Kyle Schlitt

Extending M.\ Daws' definition of ultra-amenable Banach algebras, we introduce the notion of operator ultra-amenability for completely contractive Banach algebras. For a locally co…

Connes-amenability of Fourier--Stieltjes algebras

Volker Runde, Faruk Uygul

Let $G$ be a locally compact group, and let $B (G)$ denote its Fourier--Stieltjes algebra. We show that $B (G)$ is Connes-amenable if and only if $G$ is almost abelian.

Factorization of completely bounded maps through reflexive operator spaces with applications to weak almost periodicity

Volker Runde

Let $(M, Γ)$ be a Hopf--von Neumann algebra, so that $M_{*}$ is a completely contractive Banach algebra. We investigate whether the product of two elements of $M$ that are both wea…

Completely almost periodic functionals

Volker Runde

Using the notion of complete compactness introduced by H. Saar, we define completely almost periodic functionals on completely contractive Banach algebras. We show that, if $(M, Γ)$ …

A new and simple proof of Schauder's theorem

Volker Runde

Schauder's theorem asserts that a bounded linear operator between Banach spaces is compact if ad only if its adjoint is. We give a new proof of this result, which is both short and…
