摘要
By using the modified Clarkson–Kruskal(CK)direct method,we obtain the non-Lie symmetry group of the two-dimensional KdV-Burgers equation.Under some constraint conditions,Lie point symmetry is also obtained.Through the symmetry group,some new exact solutions of the two-dimensional KdV-Burgers equation are found.
