A Hamilton-Jacobi theory for hydrodynamic limit of global action minimizing collective dynamics
Abstract
We take a variational approach to understand hydrodynamic limit of (global) action minimizing Lagrangian collective dynamics, of weakly interacting deterministic particles.
We convert the problem into one of studying multi-scale limit theorems on Hamilton-Jacobi equation in space of probability measures. We derive an effective Hamiltonian and its associated variational problem. We make extensive use of recent theories on optimal transport, first order analysis in Alexandrov metric spaces (for understanding the PDEs involved), and the weak KAM theory in finite dimensions (for the averaging step which implicitly connects with micro-canonical ensemble type arguments).
