NEW ANALYTICAL METHOD FOR CUBIC KLEIN-GORDON EQUATION.

In this paper, the (2+1)-D cubic Klein-Gordon model is investigated, which is used to described the propagation of dislocation in crystals. A simple and efficient analytical technology is successfully employed to seek some new periodic and solitary wave solutions, which is called sine-cosine method. The physics properties of these obtained periodic and solitary wave solutions are illustrated by corresponding graphs. [ABSTRACT FROM AUTHOR]
