Abstract

We prove that if two germs of irreducible complex analytic curves at 0C20\in\mathbb{C}^2 have different sequence of characteristic exponents, then there exists 0<α<10<\alpha<1 such that those germs are not α\alpha-H\"older homeomorphic. For germs of complex analytic plane curves with several irreducible components we prove that if any two of them are α\alpha-H\"older homeomorphic, for all 0<α<10<\alpha<1, then there is a correspondence between their branches preserving sequence of characteristic exponents and intersection multiplicity of pair of branches. In particular, we recovery the sequence of characteristic exponents of the branches and intersection multiplicity of pair of branches are Lipschitz invariant of germs of complex analytic plane curves.
