摘要：A goal of dynamical systems is to explain, quantify and predict complex phenomena in science and engineering. These phenomena include periodic and oscillatory motions, heteroclinic and homoclinic motions, diffusion, transport, and critical transitions. Tipping is a class of phenomena depicting critical or abrupt transitions from one dynamical regime to another. Oftentimes, these small likelihood transitions have significant consequences or devastating impacts. Thus, early detection and prediction of tipping is crucial for understanding and mitigating these phenomena. Stochastic dynamical systems are suitable frameworks for investigating tipping phenomena.
The speaker will present an overview about recent advances in the study of tipping phenomena in some stochastic biodynamical systems, including historical background, techniques, and indicators for early warning or early detection of tipping.
