內(nèi)容摘要:
In this talk, we construct the Hermite-Galerkin spectral schemes for two kinds of nonlinear PDEs with fractional Laplacian in multidimensional unbounded domains: One is the coupled fractional Gordon-type systems, and the other is the Klein-Gordon-Schr?dinger equations. Applying Hermite-Galerkin spectral method in space and finite difference method in time, we establish the linearized fully discrete scheme for the nonlinear problems. Several numerical examples are conducted to show the accuracy, stability, and applications of the schemes.
