摘要/Abstract

摘要：

迄今为止, 几乎没有学者研究 Schrödinger 或 Klein-Gordon 方程的概自守动力学. 该文结合 Galerkin 方法、 Laplace 变换、Fourier 级数和 Picard 迭代研究了带有非局部 Laplace 算子饱和 Schrödinger-Klein-Gordon 方程的概自守弱解的一些结果. 此外, 还考虑了该方程的全局指数收敛性.

关键词: Schr?dinger, Klein-Gordon, Galerkin 方法, Fourier 级数, Picard 迭代

Abstract:

To the best of the authors' knowledge, almost no literature focuses on the almost automorphic dynamics to Schrödinger or Klein-Gordon equations. This paper gives some results on almost automorphic weak solutions to a nonlocal Laplacian saturating Schrödinger-Klein-Gordon equations by employing a mix of Galerkin method, Laplace transform, Fourier series and Picard iteration. Beyond that, global exponential convergence of the equations is investigated.

Key words: Schr?dinger, Klein-Gordon, Galerkin method, Fourier series, Picard iteration
