Abstract

High-precision numerical scheme for nonlinear hyperbolic evolution equations is proposed based on the spectral method. The detail discretization processes are discussed in case of one-dimensional Klein-Gordon equations. In conclusion, a numerical scheme with the order of total calculation cost O(Nlog2N)O(N \log 2N) is proposed. As benchmark results, the relation between the numerical precision and the discretization unit size are demonstrated.
