Abstract

 In this paper, the invariant subspace method is generalized and improved and is then used to have an exact solution for a wide class of the linear/ non-linear mixed fractional partial differential equations $(FPDEs)$; with constant, non-constant coefficients.  Some examples are given here to illustrate the efficiency of this method.
