• Resumen

  • In this paper, we obtain the Laurent Padé Approximats (LPA) to a given formal Laurent series, as a Laurent Padé-Type Aproximant (LPTA) of higher order, in a similar way as the process carried out by Brezinski ((!])., for the classic case. For this purpose a new concept of Padé-Type Approximant to a Laurent series is introduced.
