摘要 利用Melnikov方法研究了具有扰动项的(2+1)维Boussinesq方程的同宿轨道和混沌运动.由Smale-Birkhoff定理可知有混沌现象,并获得了系统出现混沌运动的条件. Homoclinic orbitsand chaotic behaviour for(2+1)-dimensional Boussinesq equation is studied under perturbation using the Melnikov method.Chaos is arisied from Smale-Birkhoff theorem.The system conditions for chaoticmotion are found.
