Abstract:
We study a class of discrete-time bidirectional ring neural
network model with delay. We discuss the asymptotic stability
of the origin and the existence of Neimark-Sacker bifurcations,
by analyzing the corresponding characteristic equation.
Employing M-matrix theory and the Lyapunov functional method,
global asymptotic stability of the origin is derived.
Applying the normal form theory and the center manifold theorem,
the direction of the Neimark-Sacker bifurcation and the stability
of bifurcating periodic solutions are obtained. Numerical simulations
are given to illustrate the main results.
