摘要:In this talk, we discuss the existence and the limiting behavior of measure attractors of distribution laws of the solution segment process for the McKean-Vlasov stochastic p-Laplace lattice system with time delay driven by Levy noise. The nonlinear drift and diffusion terms areallowed to have superlinear growth. Due to time delay, the Skorohod metric space is employed to describe the trajectories of the solutions with jumps. We first prove the existence and uniqueness of cadlag solutions for the lattice system, and define a non-autonomous cocycle acting on theBorel probability measures in the Skorohod space. This cocycle is continuous in bounded subsets of the space of probability measures only when time is sufficiently large. We then prove the existence of pullback absorbing sets and the asymptotic compactness of the cocycle as wellas the existence and uniqueness of pullback measure attractors. We finally investigate the limiting behavior of measure attractors of the lattice system without delay as the noise intensity approaches zero. This is joint work with Zhang Chen and Xiaoxiao Sun.
