Convergence rate of Padé-type approximants for Stieltjes functions.

For a wide class of Stieltjes functions we estimate the rate of convergence of Padé-type approximants when the number of fixed poles represents a fixed proportion with respect to the order of the rational approximant. © 1998 Elsevier Science B.V. All rights reserved.
