摘要：

In this paper we characterize the derivations from (sic)(p)((G) over cap) into (sic)(q)((G) over cap), 1 <= p, q <= infinity. We find necessary and sufficient conditions for weak amenability of Banach algebras (sic)(p)((G) over cap), 1 <= p <= infinity. Moreover we find a necessary condition for the weak amenability of the convolution Banach algebra A (G) on a compact group G, where its sufficiency was proved earlier by Ghahramani and Lau.
