A class of Hopfield neural networks with conformable fractional derivative is studied. Sufficient conditions are derived for the existence and uniqueness of the equilibrium point of the network. Moreover, by using a Lyapunov function exponential stab

We consider a population model with piecewise constant argument under impulse effect. First, we deal with the model with impulses. Sufficient conditions for the oscillation of the solutions are obtained. We also investigate asymptotic behavior of the
