Solving the Fokker–Planck Equation of Discretized Dean–Kawasaki Models with Functional Hierarchical Tensor
Abstract. We propose a particle-based workflow for approximating the time-dependent law of finite-volume discretizations of the Dean–Kawasaki model. After discretization, the state is a nonnegative vector whose total mass is conserved by the finite-volume scheme, and it is therefore supported on a probability simplex....
