Abstract In this paper, a Kansa's method is designed to solve numerically the Monge-Ampère equation. The primitive Kansa's method is a meshfree method which applying the combination of some radial basis functions (such as Hardy's MQ) to approximate the solution of the linear parabolic, hyperbolic and elliptic problems. But this method is deteriorated when is used to solve nonlinear partial differential equations. We approximate the solution in some local triangular subdomains by using the combination of some cubic polynomials. Then the given problems can be computed in each subdomains independently. We prove the stability and convergence of the new method for the elliptic Monge-Ampère equation. Finally, some numerical experiments are presented to demonstrate the theoretical results.
