Abstract:Using the method of dynamical systems, the exact traveling wave solutions for the (2 +1)-dimension Gardner (2DG) equation are studied. The sufficient conditions to guarantee the existence of smooth solutions are a- chieved by studying the phase diagrams in different parameter regions, and the exact explicit parametric representa- tions of some solitary wave solutions and periodic wave solutions with different parametric are given.
Keywords:(2+1)-dimension Gardner (2DG) equation  solitary wave solution  periodic wave solution  method of dynamical systems
