Faber Polynomials, Grunsky Matrix and Period Matrices

We extend the idea of Grunsky operator and Faber operator to higher genus compact Riemann surfaces with one boundary curve. In this talk, I will first review the classical concept of Faber Polynomials corresponding to the map $f$, a conformal map on a simply connected domain $ extbf{D}$ of the Riemann sphere with $Gamma=partial f ( extbf{D})$. We define the Grunsky coefficients associated to $f$, and review the necessary and sufficient conditions for $f$ to be univalent on $ extbf{D}$. We will define Grunsky and Faber operators and show that the Faber operator is an isomorphism for quasi-circles. I will present some recent work of m ...
