A posteriori existence for the Keller-Segel model via a finite volume - finite element scheme
Marc Hoffmann, Jan Giesselmann
We derive two forms of conditional a posteriori error estimates for a finite volume scheme approximating the parabolic-elliptic Keller-Segel system. The estimates control the error…

Entropic Semi-Martingale Optimal Transport
Jean-David Benamou, Guillaume Chazareix, Marc Hoffmann +2
Entropic Optimal Transport (EOT), also referred to as the Schrödinger problem, seeks to find a random processes with prescribed initial/final marginals and with minimal relative e…
