Abstract

A simple observation about embeddings of smooth Banach spaces into $C(K)$ spaces allows us to construct a parametrization of the separable Banach spaces using closed subsets of the interval $[0,1]$. The same idea is applied to the study of the isometric embedding of $\ell _p$ spaces into certain $C(K)$ spaces with the additional condition that the functions of the image must be Lipschitz with respect to a fixed finer metric on $K$. The feasibility of that kind of embeddings is related to Szlenk indices.
