On Bivariate Quadratic Hermite-Padé Approximation

摘要：

The existence and local behavior is analysed of the off-diagonal bivariate quadratic Padé approximation to a bivariate function which has a given power series expansion about the origin. It is shown that the off-diagonal bivariate quadratic Hermite-Padé form always defines a bivariate quadratic function and that this function is analytic in a neighborhood of the origin.
