报告题目: Uniform Poincare inequalities and logarithmic Sobolev inequalities for mean field particle systems
报告人:刘伟 教授(武汉大学)
报告时间:2023年5月8日15:00-16:00
报告地点: 科技楼514
报告内容:In this talk we show some explicit and sharp estimates of the spectral gap and the log-Sobolev constant for mean field particles system, uniform in the number of particles, when the confinement potential have many local minimums. Our uniform log-Sobolev inequality, based on Zegarlinski’s theorem for Gibbs measures, allows us to obtain the exponential convergence in entropy of the McKean-Vlasov equation with an explicit rate constant, generalizing the result of Carrillo-McCann-Villani(2003) by means of the displacement convexity approach, or Malrieu(2001,2003) by Bakry-Emery technique or the recent work of Bolley-Gentil-Guillin by dissipation of the Wasserstein distance. This talk is based on a joint work with Arnaud Guillin, Liming Wu and Chaoen Zhang.
