摘要：

The generalized notion of weak amenability, namely (phi, psi)-weak amenability, where phi, psi are continuous homomorphisms on a Banach algebra A, was introduced by Bodaghi, Eshaghi Gordji and Medghalchi (2009). In this paper, the (phi, psi)-weak amenability on the measure algebra M(G), the group algebra L-1(G) and the Segal algebra S-1(G), where G is a locally compact group, are studied. As a typical example, the (phi, psi)-weak amenability of a special semigroup algebra is shown as well.
