非线性弦振动方程的新周期解

New periodic wave solutions for the equation of nonlinear vibrating string

利用改进的双曲函数法,借助一个推广形式的Riccati方程组,得到了非线性弦振动方程新周期解,这种方法同样也适用于求解其他非线性偏微分方程.

Study the equation of Nonlinear Vibrating String equation by using a improved projective Riccati equations method. As a result, some new periodic wave solutions are obtained,It indicates that the method is also suitable for solving other nonlinear evolution equations.
