An efficient computational technique for solving the Fokker-Planck equation with space and time fractional derivatives

This paper presents numerical solutions of the linear and nonlinear fokker-planck partial differential equations [fppdes] with space and time fractional derivatives through analytical solutions. these are treated by two analytical methods,namely,fractional reduced differential transform method [frdtm] and fractional variational iteration method [fvim] followed by some examples. numerical results obtained by both frdtm and fvim are compared with some existing methods in the literature. this comparison shows the supremacy of frdtm over fvim and existing methods in terms of accuracy,simplicity and reliability. © 2015 the authors.
