Abstract
In the present work, a new definition of multivariate Padé approximation of a given function which has a convergent power series form is introduced. This approximation is called multivariate perturbed Padé approximation. The error of the introduced approximation vanishes at some points in the square [0, 0.5]2. A comparison of the results obtained by our introduced approximation and the well-known Canterbury Approximation (proposed by J. Chisholm and his colleagues) is given.
