Bakry-Emery theory and renormalisation

I will discuss an approach to log-Sobolev inequalities that  combines the Bakry-Emery theory with renormalisation and present several  applications. These include log-Sobolev inequalities with polynomial  dependence for critical Ising models on Z^d when d>4 and singular SPDEs  with uniform dependence of the log-Sobolev constant on both the  regularisation and the volume. The talk is based on joint works with  Thierry Bodineau and Benoit Dagallier.

This seminar will be held on Zoom. They will also project the Zoom in the seminar room G-10 at CMSA, 20 Garden Street. For more information on how to join, please see: https://cmsa.fas.harvard.edu/event_category/probability-seminar/
