In this article, three-level implicit difference schemes of O(k4+ k2h2+ h 4) where k>0, h>0 are grid sizes in time and space coordinates, respectively, are proposed for the numerical solution of one, two and three space-dimensional nonlinear wave equations in polar coordinates subject to appropriate
