Stability of stochastic delay neural networks. (English) Zbl 0991.93120
The stochastically perturbed network with delays $dx(t)= \bigl[ -Bx(t)+ Ag\bigl(x_\tau (t)\bigr) \biggr]dt +\sigma\bigl( x(t),x_\tau (t), t\bigr)dw(t), t\geq 0;\;x(s)=\xi(s),\;-\tau\leq s\leq 0;\tag{1}$ is considered. Here $$w(t)$$ is an $$m$$-dimensional Brownian motion, $$\sigma(x,y,t)$$ is locally Lipschitz continuous and satisfies the linear growth conditions.
Several sufficient criteria are established for almost sure exponential stability of (1).
