“…The dynamics of systems of the form (1) have been studied by many authors, see for instance [5,11,29,36] and the references therein. Recently, the existence of attractors for Lamé systems were investigated in [3,6,7,17,19,28,40].…”
We investigate the dynamics of a nonlinear Lamé lattice system with nonlinear damping. Under certain conditions on the nonlinear terms, we prove the global well-posedness of the initial value problem in a suitable space and the existence of a global attractor for the associated semigroup. Moreover, we study the upper semicontinuity of attractors when the sum of the Lamé constants in the discrete elasticity operator tends to zero.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
