Abstract: | Let be a locally compact group, the Banach algebra defined by Herz; thus is the Fourier algebra of . Let the dual, a closed ideal, with zero set , and . We consider the set of topologically invariant means on at , where is ``thin.' We show that in certain cases card and does not have the WRNP, i.e. is far from being weakly compact in . This implies the non-Arens regularity of the algebra . |
