Abstract:

Let G be a locally compact group with Fourier algebra $A(G)$. We prove that if G is amenable then every centralizer of $A(G)$ is determined by multiplication with an element of the Fourier-Stieltjes algebra of G. This result is then used to show that isometric centralizers correspond to characters of G.
