The commonly defined fractional derivatives, like Riemann-Liouville and Caputo ones, are
non-local operators which have the long-term memory characteristic, since they are in …

This paper is concerned with the numerical stability of time fractional delay differential
equations (F-DDEs) based on Grünwald–Letnikov (GL) approximation for the Caputo …

The Lyapunov function method is a powerful tool to stability analysis of functional differential
