The sine-cosine method and tanh method are used to construct exact solitary wave,solitary pattern and compacton solutions of the generalized (2+1)-dimensional nonlinear evolution equation.The compacton solutions,solitary wave solu-tions,and solitary pattern solutions of the generalized (2+1)-dimensional BKP equation are obtained.It is shown that the sine-cosine method tanh method are powerful tools for solving a great many nonlinear partial differential equations in mathe-matical physics.
