Renormalization groups, transport maps, and multiscale Bakry-Émery criteria
A talk in the Oberseminar Analysis series by
Yair Shenfeld
| Abstract: |
One of the important theoretical tools of the last 70 years in quantum and statistical field theories is the renormalization group in its various incarnations. In this talk, I will provide a new perspective on the subject by showing how Polchinski's exact version of the renormalization group gives rise, via the multiscale Bakry-Émery criterion, to Lipschitz transport maps between Gaussian free fields and quantum and statistical field theories. Consequently, many functional inequalities can be verified for the latter field theories, going beyond the current known results.
