Attractors for non-autonomous retarded lattice dynamical systems

Tomás Caraballo, Francisco Morillas, José Valero (2015)

Nonautonomous Dynamical Systems

In this paperwe study a non-autonomous lattice dynamical system with delay. Under rather general growth and dissipative conditions on the nonlinear term,we define a non-autonomous dynamical system and prove the existence of a pullback attractor for such system as well. Both multivalued and single-valued cases are considered.

Propagation of delayed lattice differential equations without local quasimonotonicity

Shuxia Pan (2015)

Annales Polonici Mathematici

This paper is concerned with the traveling wave solutions and asymptotic spreading of delayed lattice differential equations without quasimonotonicity. The spreading speed is obtained by constructing auxiliary equations and using the theory of lattice differential equations without time delay. The minimal wave speed of invasion traveling wave solutions is established by investigating the existence and nonexistence of traveling wave solutions.
