computing entropy production rates and chemotaxis dynamics in high dimensions by stochastic interacting particle methods
abstract:
we study stochastic interacting particle methods with and without field coupling for high dimensional concentration and singularity formation phenomena. in case of entropy production of reverse-time diffusion processes, the method computes concentrated invariant measures mesh-free up to dimension 16 at a linear complexity rate based on solving a principal eigenvalue problem of non-self-adjoint advection-diffusion operators. in case of fully parabolic chemotaxis nonlinear dynamics in 3d, the method captures critical mass for finite time singularity formation and blowup time at low costs through a smoother field without relying on self-similarity.
