Abstract

We describe the two sets of meromorphic univalent functions in the class Σ\Sigma, for which the sequence of Faber polynomials {Fj}j=1\{F_j\}_{j=1}^\infty have the roots with following properties respectively: j=1nFj(z0)=0<Fn+1(z0),\sum_{j=1}^{n}|F_j(z_0)|=0<|F_{n+1}(z_0)|, nN,n\in\mathbb N, and F1(z0)>0=j=2Fj(z0)|F_1(z_0)|> 0=\sum_{j=2}^{\infty}|F_j(z_0)|. We found an explicit form of Faber polynomials for such functions.
