We make use of fractional derivative, recently proposed by Caputo and Fabrizio, to modify the nonlinear Nagumo diffusion and convection equation. The proposed fractional derivative has no singular kernel
considered as a filter. We examine the existence of the exact solution of the modified equation using the
method of fixed-point theorem. We prove the uniqueness of the exact solution and present some numerical
- Nonlinear Nagumo equation
- Caputo-Fabrizio derivative
- fixed-point theorem
