%X The exact solutions of the (2 1) dimensional Sawada Kodera(SK) equation are presented by using the bilinear method.The N breather solutions,the solution to describe the interaction between a line solition and a y periodic soliton and the solution to express the interaction between two y periodic soliton are included in the exact solutions.Detailed behaviors of interactions between two y periodic solitons are illustrated both analytically and graphically.For SK equation,the value of interactive constant can only be taken in some range.We can only obtain the repulsive interaction that keeps the shapes of soliton unchanged.
