该文研究R~(3+)中的非线性Schrdinger-Klein-Gordon耦合方程组的Cauchy问题,在对非线性项和初值的适当假设下,运用粘性方法,能量方法以及紧性讨论,证明了整体弱解的存在性.
In this paper,the Cauchy problem to the nonlinear Schrdinger-Klein-Gordon equations in 3+1 time-space is studied.Under certain assumptions on nonlinear terms and the initial data,the existence of global weak solutions is obtained by the viscous method and the energy method combined with the compactness arguments.
