報(bào)告人簡(jiǎn)介：

顧陳琳現(xiàn)為清華大學(xué)丘成桐數(shù)學(xué)科學(xué)中心助理教授，他本科畢業(yè)于復(fù)旦大學(xué)，博士畢業(yè)于巴黎高等師范學(xué)院，師從Jean-Christophe Mourrat。他主要從事概率論和偏微分方程研究，重點(diǎn)關(guān)注定量均勻化理論、隨機(jī)環(huán)境下的隨機(jī)游動(dòng)、交互粒子系統(tǒng)、分支過(guò)程等方面，相關(guān)工作發(fā)表在AOP、PTRF、AAP等國(guó)際期刊上。

報(bào)告摘要：

For the conservative particle systems in infinite volume, the relaxation to equilibrium is expected to be a Gaussian-type decay. The sharp decay rate was known for two models -SSEP by Bertini and Zegarlinski, and zero-range processes by Janvresse, Landim, Quastel and Yau - and they are btained via different methods. This talk aims to unify the two existing approaches with homogenization, and presents the result in speed-change exclusion rocesses. The talk is based on a joint work with Linzhi Yang.
