Exp-function method for constructing exact solutions of Sharma–Tasso–Olver equation

In this paper we use the Exp-function method for the analytic treatment of Sharma–Tasso– Olver equation. New solitonary solutions are formally derived. Change of parameters, which drastically changes the characteristics of the equations, is examined. It is shown that the Exp-function method provides a powerful mathematical tool for solving high-dimensional nonlinear evolutions in mathematical physics. The proposed schemes are reliable and manageable.
