| Abstract: | Based on the homogenous balance method and the trial function method,several trial function methods composed of exponential functions are proposed and applied to nonlin-ear discrete systems.With the help of symbolic computation system,the new exact solitary wave solutions to discrete nonlinear mKdV lattice equation,discrete nonlinear(2 1) dimen-sional Toda lattice equation,Ablowitz-Ladik-lattice system are constructed.The method is of significance to seek exact solitary wave solutions to other nonlinear discrete systems. |
