Approximate Weak Amenability, multipliers and derivations of Segal algebras
by
Fereidoun Ghahramani
University of Manitoba

Let G be a locally compact group, L1(G) be the group algebra and S1(G) be a Segal subalgebra of L1(G). We show that when G is a SIN group S1(G) is approximately weakly amenable (previously we had this result under the additional assumption that G was amenable). For a compact group G we characterize multipliers and derivations from the Lebesgue-Fourier algebra LA(G) into itself and into its second dual and we show that LA(G) is Arens regular. This is joint work with Tony Lau.
