On the convergence of Chebyshev--Padé approximations to real-valued algebraic functions

preprint2010arXivOpen access

Abstract

We announce some new results on the convergence of Chebyshev--Padé approximations to real-valued algebraic function given on the segment [−1,1][-1,1]. The rate of convergence on the segment and in the corresponding maximal domain of meromorphity of a given function is charactirized in terms of a theoretical potential equilibrium problem.
