[Abstract-pdf] [Abstract-ps] In this note the class $\Lip_{\alpha(t)}$ of continuous functions is introduced. The definition is arranged so that for the constant function $\alpha(t) \equiv \alpha$, the class $\Lip_{\alpha(t)}$ is nothing but the classical Lipschitz space $\Lip_\alpha$. Then, to justify that our set of axioms for $\alpha(t)$ are properly chosen, some celebrated theorems of Privalov, Titchmarsh, Hardy and Littlewood about $\Lip_\alpha$ functions are shown to be also valid for $\Lip_{\alpha(t)}$ functions. Keywords: Lipschitz functions, test function, associated test function, Hilbert transform, Hardy classes. MSC 2000: Primary 26A16; Secondary 32A40. [FullText-pdf (265 K)] [FullText-ps (459 K)]
