Abstract
The importance of Pade approximation has been increasingly recognized in '
recent years. The first convergence result of Pade approximants valid for general
meromorphic functions was obtained by de Montessus de Ballore in 1902. He
proved that when a function f has precisely n poles in I z 1< R, then the (n+ 1)th
column in thePade table of f converges to f in I z J< R. (Abbreviation abstract)
