一类非线性发展方程的精确解

Exact Solutions of a Type of Nonlinear Evolution Equation

利用扩展的tanh法考虑了(2+1)维高阶水波方程,并得到了一些新的精确解.这些解对于解释复杂的物理现象有重要的作用.

The extended tanh method with a computerized symbolic computation is used for con- structing the travelling wave solutions of nonlinear equation of evolutions. In this paper, we show that the extended tanh method can be applied readily to generate exact soliton solutions of generalized forms of water wave equations.
