Abstract：

Many natural and social phenomena exhibit randomness due to the complexity of interactions, incomplete information, or intrinsic stochastic behavior. From molecular fluctuations to financial markets, probability theory provides a fundamental framework for modeling and understanding uncertainty. These diverse applications highlight its versatility as a lens for studying complexity.

In this lecture, we explore stochastic dynamical systems, where randomness, noise, and ergodicity play a fundamental role in shaping characteristic behavior. We will see how probability theory not only explains uncertainty but also uncovers deep structural properties of dynamical systems.

About the speaker：

Xue-Mei Li is a professor of mathematics at Imperial College London and at Swiss Federal Institute of Technology Lausanne. Her research spans a wide range of topics, including stochastic differential equations, stochastic partial differential equations, stochastic processes on manifolds, and contemporary challenges in fluctuation problems, coarse curvatures, multi-scale equations, and non-Markovian dynamics with long-range correlations.
