12. On some nonlinear evolution systems which are perturbations of Wasserstein gradient flows
-
Maxime Laborde
Abstract
This chapter presents existence and uniqueness results for a class of parabolic systems with nonlinear diffusion and nonlocal interaction. These systems can be viewed as regular perturbations ofWasserstein gradient flows. Here,we extend results known in the periodic case [1] to the whole space and on a smooth bounded domain. Existence is obtained using a semi-implicit Jordan-Kinderlehrer-Otto scheme and uniqueness follows from a displacement convexity argument.
