Uncountable Infinite Exact Solutions to the FitzHugh-Nagumo Model
Shahid Sultan Ali Ramji, Eddy Kwessi, Mujahid Abbas
First time in six decades, uncountable infinite exact solutions of FitzHugh-Nagumo model with diffusion have been found. FitzHugh-Nagumo model is a nonlinear dynamical system appli…
