Analytical approach for space-time fractional Klein-Gordon equation

In this work, we find exact solutions of space-time fractional Klein-Gordon equation including Jumarie's modified Riemann-Liouville derivative by using fractional complex transform, (G′/G) and (w/g)-expansion methods which is employed to solve fractional differential equations in mathematical physics and applied mathematics. As a result, two types of exact solutions are obtained. It is shown that the considered transform and method are very efficient and powerful in solving other kinds of nonlinear fractional differential equations.
