| Abstract: | Applying the modified Clarkson-Kruskal direct method, the classical Lie point symmetry of the generalized coupled Hirota- Satsuma KdV system was derived. The similarity reduction and exact solutions of the system were obtained by applying the given Lie symmetry. At the same time, the relationship between the old and new solutions was set up, which generalized the new solutions. |
