报告摘要: After many deep investigations in the theory of dynamical systems in the last several decades, people found that structural stability seems to be too strong a requirement from both theoretical and practical points of view. In the other hand, with the development of ergodic theory and random dynamical systems, people realize gradually that stochastic stability is a notion more natural and appropriate than structural stability, and have found a number of cases which are not structurally stable but are stochastically stable. In this report we will introduce the notions of stochastic stability and discuss two main approaches in this field. As the main results of the report, we show stochastic stability of a class of partially expanding attractors and of fat solenoidal attractors.
