(Non-)amenability of the Fourier algebra in the cb-multiplier norm
Volker Runde
For a locally compact group , let denote its Fourier algebra, the completely bounded multipliers of , and the closure of 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…
On positive definiteness over locally compact quantum groups
Volker Runde, Ami Viselter
The notion of positive-definite functions over locally compact quantum groups was recently introduced and studied by Daws and Salmi. Based on this work, we generalize various well-…
Connes-amenability of Fourier--Stieltjes algebras
Volker Runde, Faruk Uygul
Let be a locally compact group, and let denote its Fourier--Stieltjes algebra. We show that is Connes-amenable if and only if is almost abelian.
Ergodic theory for quantum semigroups
Volker Runde, Ami Viselter
Recent results of L. Zsido, based on his previous work with C. P. Niculescu and A. Stroh, on actions of topological semigroups on von Neumann algebras, give a Jacobs-de Leeuw-Glick…
Why Banach algebras?
Volker Runde
We give a brief overview of the area of Banach algebras, intended for a general mathematical audience.
