Title: Existence and upper semicontinuity of random attractors for stochastic p-Laplacian equations on unbounded domains Authors: Jia Li (Southwest Univ., Chongqing, China) Yangrong Li (Southwest Univ., Chongqing, China) Hongyong Cui (Southwest Univ., Chongqing, China) Abstract: The existence of a pullback attractor is established for a stochastic p-Laplacian equation on $\mathbb{R}^n$. Furthermore, the limiting behavior of random attractors of the random dynamical systems as stochastic perturbations approach zero is studied and the upper semicontinuity is proved.
