Rate of pole detection using Padé approximants to polynomial expansions

Padé approximations constructed from orthogonal and Faber polynomials on some compact set EE serve as tools to detect poles of an approximated function around the set EE. The goal of this article is to study the rate of such pole detection using indicators introduced by Gonchar (Poles of rows of the...
