Gg. Xu, AMENABILITY AND UNIFORMLY CONTINUOUS FUNCTIONALS ON THE ALGEBRAS A(P)(G) FOR DISCRETE-GROUPS, Proceedings of the American Mathematical Society, 123(11), 1995, pp. 3425-3429
In this paper, it is shown that for every discrete group G and 1 < p <
infinity, A(p)(G) . PM(p)(G) is closed in PM(p)(G) if and only if G i
s amenable.
