✦ Synopsis


In previous papers the convergence of sequences of rectangular'' multivariate Pade -type approximants was studied. In other publications definitions of triangular'' multivariate Pade -type approximants were given. We extend these results to the general order definition where the choice of the denominator polynomial is completely free. Also we develop convergence theorems and we distinguish between results obtained in polydiscs and in multivariate balls. The numerical examples section illustrates this difference and compares the obtained results with the approximation power of general order multivariate Pade approximants.

The nested multivariate Pade approximants were recently introduced. In the case of two variables x and y, they consist in applying the Pade approximation with respect to y to the coefficients of the Pade approximation with respect to x. The principal advantage of the method is that the computation o

A comparison is made between Pade and Pade -type approximants. Let Q n be the n th orthonormal polynomial with respect to a positive measure + with compact support in C. We show that for functions of the form where w is an analytic function on the support of +, Pade -type approximants with denomina
