The exp-function method for solving nonlinear space-time fractional differential equations inmathematical physics

Abstract EN

Using the Exp-function method, we derive exact solutions of the nonlinear space–time fractional Telegraph equation and space–time fractional KPP equation.

As a result, we obtain many exact analytical solutions including hyperbolic function.

The fractional derivative is described in Jumarie’s modified Riemann–Liouville sense.

This method is very effective and convenient for solving nonlinear fractional differential equations.
