Criteria for Finite-Time Convergence in Discrete Variable-Order Fractional FitzHugh–Nagumo Reaction–Diffusion Systems

European Journal of Pure and Applied Mathematics
This study addresses the problem of finite-time stability (FTS) for a discrete-time FitzHugh–Nagumo reaction–diffusion system (FHN–RDs) governed by a variable-order (VO) Caputo fractional difference operator.

Nagumo and Landesman-Lazer type conditions for nonlinear second order systems

Nonlinear Differential Equations and Applications NoDEA, 2007
We study the existence of solutions for a nonlinear second order system of ordinary differential equations under various boundary conditions. Assuming suitable Nagumo type conditions we prove the existence of at least one solution applying the method of upper and lower solutions.

Quasi-period, periodic bursting and bifurcations in memristor-based FitzHugh-Nagumo circuit

AEU - International Journal of Electronics and Communications, 2019
A third-order non-autonomous memristor-based FitzHugh-Nagumo (FHN) circuit is proposed through introducing a memristor emulator to realize the nonlinear function of the membrane voltage in the FHN model.

A Sufficient Condition for 2-Contraction of a Feedback Interconnection

IEEE Transactions on Automatic Control
We derive a new sufficient condition for 2-contraction of a feedback interconnection of two nonlinear dynamical systems. Our condition is based on, first, deriving new formulas for the 2-multiplicative [2-additive] compound of block matrices using block ...
