Exact travelling wave solutions of the discrete sine-Gordon equation obtained via the exp-function method. (English) Zbl 1183.34101
From the authors’ abstract: We generalize the exp-function method for solving nonlinear differential-difference equations. As an illustration, two series of exact travelling wave solutions of the discrete sine-Gordon equation are obtained. As some special examples, these new exact travelling wave solutions can degenerate into the kink-type solitary wave solutions.
