It can obtain the reduced theorems of eigenequation of conjugate systems with repeated units by using projection operators of symmetry plane and symmetry axis one after another. On certain condition, it can apply to the two-dimensional and three-dimensional conjugate systems.展开更多

The equation can be reduced to the Caudrey–Dodd–Gibbon equation, Savada–Kotera equation and the Kaup–Kupershmidt equation, etc. By means of the Lie group analysis method, the invariance properties and symmetry reductions of the equation are derived. Furthermore, by means of the power series theory, its exact power series solutions of the equation are also constructed. Finally, two kinds of conservation laws of the equation are well obtained with aid of the self-adjoint method.展开更多
