Variable-order fractional discrete models are dynamical systems described by non-integer order difference equations where the fractional order changes over discrete-time. This paper makes a contribution to the topic by presenting two nonlinear nabla variable-order models and by rigorously proving their asymptotic stability. In particular, some novel theorems are illustrated, regarding the asymptotic stability of both nonlinear nabla variable-order systems and nonlinear nabla variable-order neural networks. Finally, numerical simulations of discrete systems where the fractional order varies with nonlinear law are carried out, with the aim to show the effectiveness of the conceived theoretical approach. • Stability of VFO systems with discrete nabla operator. • Stability of discrete VFO neural networks. • Numerical examples.
