摘要：We apply the (G'/G) method to seek exact solutions for several fractional partial differential equations including the space- time fractional (2 + 1)- dimensional dispersive long wave equations, the (2 + 1)- dimensional space- time fractional Nizhnik- NovikovVeselov system, and the time fractional fifth- order Sawada-Kotera equation. The fractional derivative is defined in the sense of modified Riemann-liouville derivative. Based on a certain variable transformation, these fractional partial differential equations are transformed into ordinary differential equations of integer order. With the aid of mathematical software, a variety of exact solutions for them are obtained.
