Convergence of Fourier--Padé Approximants for Stieltjes Functions
We prove convergence of diagonal multipoint Pad\'e approximants of Stieltjes-type functions when a certain moment problem is determinate. This is used for the study of the convergence of Fourier--Pad\'e and nonlinear Fourier--Pad\'e approximants for such type of functions.

Keywords:rational approximation, multipoint Padé approximants, Fourier--Padé approximants, moment problem
