| Abstract: | By applying extended hyperbolic function method,we study the saturable discrete nonlinear Schrodinger equation and obtained a number of new exact localized solutions,including discrete bright soliton solution,dark soliton solution,bright and dark soliton solution,and provide that a special relation is bound on the coefficients of the equation among the solutions obtained. |
