Abstract

‎ ‎In this paper we first study the structure of‎ ‎certain ideals of ${\rm Lip}(X,K,d^\alpha)$‎. ‎Next we show that if $K$‎ ‎is infinite‎ ‎and ${\rm int}(K)$ contains a limit point of $K$‎ ‎then ${\rm Lip}(X,K,d^\alpha)$ has‎ ‎at least a nonzero continuous point derivation‎ ‎and applying this fact we prove that ${\rm Lip}(X,K,d^\alpha)$ is‎ ‎not weakly amenable and amenable‎.X
