APPLICATION OF AN IRRATIONAL TRIAL EQUATION METHOD TO HIGH-DIMENSIONAL NONLINEAR EVOLUTION EQUATIONS

An analytic technique, an irrational trial equation method, is applied to solve the (3+1)-dimensional potential-YTSF equation and the (2+1)-dimensional Broer-Kaup- Kupershmidt equations. Using this method, some exact travelling wave solutions to two high dimensional nonlinear evolution equations are obtained. This method provides us with a new way to obtain series solutions of such problems.
