  : Let G be a locally compact group. The Fourier and Fourier- Stieltjes algebras, A(G) and B(G) are dual objects to the group and measure algebras L1(G) and M(G), respectively, in a manner which generalizes Pontryagin duality. It is now classical that L1(G) is (operator) amenable exactly when G is amenable, exactly when A(G) is operator amenable. M(G) is (operator) amenable exactly when G is discrete and abelian; hence B(G) ought to be operator amenable exactly when G is compact. This is not true, generally; but is true for connected groups.
