Abstract

‎In this work‎, ‎we apply the local Petrov-Galerkin method based on radial basis functions to solving the two dimensional linear hyperbolic equations with variable coefficients subject to given appropriate initial and boundary conditions‎. ‎Due to the presence of variable coefficients of the differential operator‎, ‎special treatment is carried out in order to apply Green's theorem and derive the variational formulation‎. ‎We use the radial point interpolation method to construct shape functions and a Crank-Nicolson finite difference scheme is employed to approximate the time derivatives‎. ‎The stability‎, ‎convergence and error analysis of the method are also discussed and theoretically proven‎. ‎Some numerical examples are presented to examine the efficiency and accuracy of the proposed method‎.
