Mean-Field Limit and Quantitative Estimates with Singular Attractive Kernels
A talk in the Bielefeld Stochastic Afternoon series by
Zhenfu Wang from Peking University
| Abstract: |
We study the mean field limit and quantitative estimates for many-particle systems with singular attractive interactions between particles. As an important example, a full rigorous derivation (with quantitative estimates) of the Patlak-Keller-Segel model in optimal subcritical regimes is obtained for the first time. To give an answer to this longstanding problem, we take advantage of a new modulated free energy and we prove some precise large deviation estimates encoding the competition between diffusion and attraction. Joint work with D. Bresch and P.-E. Jabin.
