Symmetries, exact solutions and conservation laws of Caudrey-Dodd-Gibbon-Kotera-Sawada equation
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.
