In this paper we investigate when various Banach algebras associated to a locally compact group G have the weak or weak* fixed point property for left reversible semigroups. We proved, for example, that if G is a separable locally compact group with a compact neighborhood of the identity invariant under inner automorphisms, then the Fourier-Stieltjes algebra of G has the weak* fixed point property for left reversible semigroups if and only if G is compact. This generalizes a classical result of T.C. Lim for the case when G is the circle group T. © 2009 Elsevier Inc. All rights reserved.
