We present some relations that allow the efficient approximate inversion of linear differential operators with rational function coefficients. We employ expansions in terms of a large class of ...

School of Mathematics, Jiaying University, Meizhou, China. Direct searching for exact solutions of nonlinear partial differential equations (NLPDEs) plays an important role in the study of nonlinear ...

This article describes three approximation methods I used to solve the growth model (Model 1) studied by the National Bureau of Economic Research's nonlinear rational-expectations-modeling group ...
