Abstract
Recorded 16 September 2025. Roman Shvydkoy of the University of Chicago presents "On regularity and asymptotics of kinetic alignment models" at IPAM's Embracing Stochasticity in Electrochemical Modeling Workshop.
Abstract: In this talk we discuss wellposedness, regularization, and relaxation for a broad class of Fokker-Planck-Alignment models which appear in collective dynamics and many other applications. The main feature of these results, as opposed to previously known ones, is the lack of regularity or no-vacuum requirements on the initial data. With a particular application to the classical kinetic Cucker-Smale model, we demonstrate that any bounded data with finite energy, (1+|v|2)f0∈L1
, f0∈L∞ , and finite higher moment |v|qf∈L2 , q≫2 , gives rise to a global instantly smooth solution, satisfying entropy equality and relaxing exponentially fast.
