Resumen:
This paper is dealing with the problem of finding the ?best? multipoint Pade approximant of an analytic function when data in some neighborhoods of sampling points are more important than others. More exactly, we obtain a multipointPade approximants as limits of best rational Lp-approximations on union of disks, when the measure of them tends to zero with different speeds. As such, this technique provides useful qualitative and analytic information concerning theapproximants, which is difficult to obtain from a strictly numerical treatment.
