Operator space structure and amenability for Figà-Talamanca-Herz algebras
Anselm Lambert, Matthias Neufang, Volker Runde
Column and row operator spaces - which we denote by COL and ROW, respectively - over arbitrary Banach spaces were introduced by the first-named author; for Hilbert spaces, these de…
On the Topological Centre Problem for Weighted Convolution Algebras
Matthias Neufang
Let G be a locally compact non-compact group. We show that under a very mild assumption on the weight function w, the weighted group algebra L_1(G,w) is strongly Arens irregular in…
A Unified Approach to the Topological Centre Problem for Certain Banach Algebras Arising in Abstract Harmonic Analysis
Matthias Neufang
Let G be a locally compact group. Consider the Banach algebra L_1(G)^**, equipped with the first Arens multiplication, as well as the algebra LUC(G)^*, the dual of the space of bou…
Amplification of Completely Bounded Operators and Tomiyama's Slice Maps
Matthias Neufang
Let (M,N) be a pair of von Neumann algebras, or of dual operator spaces with at least one of them having property S_σ, and let T be an arbitrary completely bounded mapping on M. We…
