摘要: In this paper, We study the global attractor and its properties on infinite lattice dynamical system FitzHugh-Nagumo in a weighted space lσ2×lσ2. We prove the existence and uniqueness of the solution to the lattice dynamical system FitzHugh-Nagumo in lσ2×lσ2. Then we get a bounded absorbing set, which suggests the existence of global attractors. Finally, we study the uniform boundedness and the upper semicontinuity of the global attractor.
