摘要: By using the extended hyperbolic function approach, we consider a quintic discrete nonlinear Schr?dinger (QDNLS) equation and obtained new exact localized solutions ,including discrete bright soliton solution, dark soliton solution, alternating phase bright soliton solution and alternating phase dark soliton solution ,if a special constraint is imposed on coefficients of the equation.
