报告题目：Multiple time scales for reaction-diffusion systems

报告时间：2025年5月28日上午10:00

报告地点：理工楼631

报告摘要：It happens often that in an interacting system, different processes take place at different time scales, on each of which the system might be described by a different model. A typical example stems from a large system of reactions, where many reactions happen with much faster rates than the others. Using this, one can obtain a reduced model by assuming that the fast reactions achieve their stationary states immediately, and this technique has been utilised quite often in chemical engineering. The rigorous, mathematical study of this phenomenon shows interesting yet challenging problems. In this talk, I will first discuss certain modelling questions leading to the multiple time scales phenomenon, and then present some common techniques to mathematically investigate the problems.
