摘要
应用改进的CK直接方法,得到了(2+1)维Caudrey-Dodd-Gibbon-Kotera-Sawada(CDGKS)方程的对称群定理。利用对称群理论和方程的旧解得到了该方程新的精确解,扩大了解的范围。最后根据对称和共轭方程求出了(2+1)维CDGKS方程的无穷多守恒律。
By using the improved CK’s method,the symmetry group theorem of（2＋1）-dimensional Caudrey-Dodd -Gibbon-Kotera-Sawada equation is derived.Some new exact solutions of（2＋1）-dimensional CDGKS equation are obtained by applying the theorem and given solutions,which expands the scope of solutions of CDGKS equation.Infinite conservation laws of（2＋1）-dimensional CDGKS equation are also found by the symmetries and adjoint equation.
