摘要： In this talk, entropy, pressure and equilibrium states are investigated for noninvertible random dynamical systems via the preimage structure. For a continuous random dynamical system, the folding entropy, preimage entropy and preimage pressure are introduced, variational principles are obtained. For a nondegenerate random partially hyperbolic dynamical system the notions of metric stable entropy and stable pressure via the preimage structure of local stable manifolds are proposed, and variational principles are established. As applications of variational principles, p-equilibrium states (resp. s-equilibrium states) and p-tangent functionals (resp. s-tangent functionals) are studied. This is a joint work with Weisheng Wu and Yujun Zhu.
