 Weak amenability of convolution Banach algebras on compact hypergroups Bull. Korean Math. Soc. 2010 Vol. 47, No. 2, 307-317 https://doi.org/10.4134/BKMS.2010.47.2.307Printed March 1, 2010 Hojjatollah Samea Bu-Ali Sina University Abstract : In this paper we find necessary and sufficient conditions for weak amenability of the convolution Banach algebras $A(K)$ and $L^2(K)$ for a compact hypergroup $K$, together with their applications to convolution Banach algebras $L^p(K)$ $(2\leq p<\infty)$. It will further be shown that the convolution Banach algebra $A(G)$ for a compact group $G$ is weakly amenable if and only if $G$ has a closed abelian subgroup of finite index.
