TITLE: Optimal Transport in Inhomogeneous Media: Convergence of Gradient Flows and the Effective Wasserstein Metric
ABSTRACT: The Fokker–Planck equation with rapidly oscillating coefficients can be formulated as a gradient flow in Wasserstein space, involving both inhomogeneous dissipation and oscillatory free energy. Using an evolutionary Gamma-convergence approach, we derive the homogenized dynamics, which retain the gradient flow structure in a limiting homogenized Wasserstein space. We will also discuss a comparison between the limiting Wasserstein distance induced by the gradient flow and the direct Gromov–Hausdorff limit of the Wasserstein distance.
