What is High-Order Method for Nonlinear Wave Equations about?

This paper presents a new high accuracy numerical method for solving three-space dimensional nonlinear wave equations, achieving an order of O(k2 + k2h2 + h4) through off-step discretization. The method requires fewer evaluations of the function g compared to previous approaches and is applicable to wave equations in polar coordinates without the need for fictitious points. The proposed algorithm demonstrates unconditional stability when applied to a telegraphic equation, supported by comparative numerical
