New Exact Solutions Of Three Nonlinear Fractional Partial Differential Equations

By using the complex transform methods,the nonlinear fractional Sharma-Tasso-Olver equation,the(3+1)-dimensional fractional Jimbo-Miwa equation and space-time fractional(2+1)-dimensional Calogero-BogoyavlenskillSchiff equation are transformed into the ordinary differential equation.Then the expanded(G?/G)expansion method is employed to solve the three fractional equation.The hyperbolic function solution,trigonometric funtion solution and rational function solution for the three equation are obtained.
