Wavelet Characterization of Inhomogeneous Lipschitz Spaces on Spaces of Homogeneous Type and Its Applications

  • Fan Wang

摘要

In this article, the author establishes a wavelet characterization of inhomogeneous Lipschitz space \(\textrm{lip}_{\theta }(\mathcal {X})\) lip θ ( X ) via Carleson sequence, where \(\mathcal {X}\) X is a space of homogeneous type introduced by R. R. Coifman and G. Weiss. As applications, characterizations of several geometric conditions on \(\mathcal {X}\) X , involving the upper bound, the lower bound, and the Ahlfors regular condition, are obtained.
