Bäcklund transformation of fractional Riccati equation and its applications to nonlinear fractional partial differential equations

In this Letter, the fractional derivatives in the sense of modified Riemann–Liouville derivative and the Bäcklund transformation of fractional Riccati equation are employed for constructing the exact solutions of nonlinear fractional partial differential equations. The power of this manageable method is presented by applying it to several examples. This approach can also be applied to other nonlinear fractional differential equations.

► Backlund transformation of fractional Riccati equation is presented.
► A new method for solving nonlinear fractional differential equations is proposed.
► Three important fractional differential equations are solved successfully.
► Some new exact solutions of the fractional differential equations are obtained.
