Abstract:

This paper deals with the existence of random attractors for the stochastic FitzHughNagumo systems with delay on infinite lattice. Under suitable dissipative conditions, it is shown that such a system has a random attractor which is a random compact invariant set.

Key words: random delay, FitzHughNagumo lattice system, random attractor, existence
