Constructive solution of Zariski's Moduli Problem for Plane Branches
Abstract
In this paper we give an explicit solution to Zariski's moduli problem for plane branches. We compute (in an algorithmic way) the set of K\"{a}hler differentials of an irreducible germ of holomorphic plane curve. We show that there is a basis of this set whose main elements correspond to dicritical foliations. Indeed, we discuss several concepts of generation for the semimodule of values of K\"{a}hler differentials of the curve and provide basis of K\"{a}hler differentials, for every of these concepts, whose geometric properties are described. Moreover, we give an algorithmic construction of the bases.
