Abstract
Recently, it has been great interest in the development of methods for solving nonlinear differential equations directly. Here, it is shown an algorithm based on Pad′e approximants for solving nonlinear partial differential equations without requiring a onedimensional reduction. This method is applied to the λφ4 model in 4 dimensions and new solutions are obtained.
