摘要
利用古典李点对称群方法研究了(2+1)维非线性Klein-Gordon方程,构建了(2+1)维Klein-Gordon方程的一维最优系统,并利用所构建的最优系统的元素对该非线性方程进行相似约化,有效地将原方程降低了一维.
Studied the ( 2+1 ) -dimensional nonlinear Klein-Gordon equations by using of the Lie group of symmetry, obtained it's one-dimensional optimal system. Also emploied elements of the optimal system to classify the Klein-Gordon equations, it can reduce the dimension of nonlinear Klein-Gordon equations
