## The discrete $$(G^{\prime}/G)$$-expansion method applied to the differential-difference Burgers equation and the relativistic Toda lattice system.(English)Zbl 1252.65112

Summary: We introduce the discrete $$(G^{\prime}/G)$$-expansion method for solving nonlinear differential-difference equations (NDDEs). As illustrative examples, we consider the differential-difference Burgers equation and the relativistic Toda lattice system. Discrete solitary, periodic, and rational solutions are obtained in a concise manner. The method is also applicable to other types of NDDEs.
