application of exp-function method to the (2 + 1)-dimensional calogero bogoyavlanskii schiff equation.

in this paper, the exp-function method, with the aid of a symbolic computation system such as maple, is applied to the (2 + 1)-dimensional calogero bogoyavlanskii schiff equation. exact and explicit generalized solitary solutions are obtained in more general forms. the free parameters can be determined by initial or boundary conditions. the method is straightforward and concise, and its applications are promising. it is shown that the exp-function method, with the help of symbolic computation, provides a very effective and powerful mathematical tool for solving calogero bogoyavlanskii schiff equation.
