A non-weakly amenable Banach algebra whose bidual is weakly amenable
Banach algebra weakly amenable
2010/11/9
We answer, in the negative, the question: Does a Banach algebra inherit weak amenability from its bidual?, which was open since 1996
A Generalization of the Weak Amenability of some Banach Algebra
Generalization Banach Algebra
2010/11/9
Let $A$ be a Banach algebra and $A^{**}$ be the second dual of it. We show that by some new conditions, $A$ is weakly amenable whenever $A^{**}$ is weakly amenable. We will study this problem under g...
