Operator amenability of Fourier-Stieltjes algebras, II

Abstract

We give an example of a non-compact, locally compact group $G$ such that its Fourier-Stieltjes algebra $B(G)$ is operator amenable. Furthermore, we characterize those $G$ for which $A^{\ast }(G)$ - the spine of $B(G)$ as introduced by M. Ilie and the second named author - is operator amenable and show that $A^{\ast }(G)$ is operator weakly amenable for each $G$.
