| Abstract: | Some new exact travelling wave and period solutions ofdiscrete nonlinear Schrödinger equation are foundby using a hyperbolic tangent function approach, which was usuallypresented to find exact travelling wave solutions of certainnonlinear partial differential models. Now we can further extendthe new algorithm to other nonlinear differential-different models. |
| Keywords: | discrete nonlinear Schrödinger equation hyperbolic tangentfunction approach solitary wave solution periodic wave solution |
