Computation of Optimal Transport with Finite Volumes
Andrea Natale, Gabriele Todeschi
We construct Two-Point Flux Approximation (TPFA) finite volume schemes to solve the quadratic optimal transport problem in its dynamic form, namely the problem originally introduce…

TPFA Finite Volume Approximation of Wasserstein Gradient Flows
Andrea Natale, Gabriele Todeschi
Numerous infinite dimensional dynamical systems arising in different fields have been shown to exhibit a gradient flow structure in the Wasserstein space. We construct Two Point Fl…
