Pullback attractors for lattice FitzHugh-Nagumo systems with fast-varying delays
摘要
Abstract
We investigate the dynamical behavior of lattice FitzHugh-Nagumo equations with fast-varying delays and prove the existence and uniqueness of pullback attractor for the equations .Generally ,stud-ying the attractors of time-varying delay equations require that the derivative of the delay term is less than 1 (slow-varying delay) .In this paper ,by using some differential inequality techniques ,we remove this constraint .Thus our method can be used to deal with equations with fast-varying delays .关键词
