报告摘要:In this talk I will explain the idea in deriving porous medium type diffusion equation through moderate interacting stochastic particle system and show the mean field limit in the sense of probability for algebraic cut-off of the singular interaction. Since the proof is rather technical, I will try to explain the main idea by using stopping time and law of large number to show that the probability of the particle trajectory away from the mean field trajectory is small. This is a part of the joint work with Alexandra Holzinger and Ansgar Jüngel on the topic of fluctuation of moderate interacting system.
