摘要
本文先用Belinsky和Zakharav(BZ)提出的真空引力场方程生解技术,以平空时度规作为种子解,生成双孤子引力行波解,并讨论了解的主要特征。然后指出,在行波情下相应场方程的求解可化为直接积分,而孤子解可从通常意义下的孤子特征出发而直接构造,并给出两个n—孤子特解的例子。
The two-soliton solutions for the gravitational travelling wave are generated with a metric of the flat space-time as a'seed' by using the solutiongenerating tecknigue for the vacuum Einstein equations which developed by Belinsky and Zakharov(BZ), and some main feature of the solutions are discussed. After that, it is point out that in the travelling wave case to solve the equations is just quadrature and a soliton solution can be constructed directly startting with solitonic character in ordinary sense; and two n-soliton special solutions are given.
