On the parametric representation of univalent functions on the polydisc

Abstract

We consider support points of the class $S^0({\mathbb{D}}^n)$ of normalized univalent mappings on the polydisc ${\mathbb{D}}^n$ with parametric representation and we prove sharp estimates for coefficients of degree 2.
