Partial Hölder Regularity for Solutions of a Class of Cross-Diffusion Systems with Entropy Structure

Marcel Braukhoff, Claudia Raithel, Nicola Zamponi

In this article we show a -partial regularity result for solutions of a certain class of cross-diffusion systems with entropy structure. Under slightly more stringent cond…

Quantitative dynamics of irreversible enzyme reaction-diffusion systems

Marcel Braukhoff, Amit Einav, Bao Quoc Tang

In this work we investigate the convergence to equilibrium for mass action reaction-diffusion systems which model irreversible enzyme reactions. Using the standard entropy method i…

Partial Hölder Regularity for Bounded Solutions of a Class of Cross-Diffusion Systems with Entropy Structure

Marcel Braukhoff, Claudia Raithel, Nicola Zamponi

In this contribution we obtain partial -regularity for bounded solutions of a certain class of cross-diffusion systems, which are strongly coupled, degenerate quasilinear…

An entropy structure preserving space-time formulation for cross-diffusion systems: Analysis and Galerkin discretization

Marcel Braukhoff, Ilaria Perugia, Paul Stocker

Cross-diffusion systems are systems of nonlinear parabolic partial differential equations that are used to describe dynamical processes in several application, including chemical c…

Global solutions for chemotaxis-Navier-Stokes system with Robin boundary conditions

Marcel Braukhoff, Bao Quoc Tang

We consider a chemotaxis-Navier-Stokes system modelling cellular swimming in fluid drops where an exchange of oxygen between the drop and its environment is taken into account. Thi…

Stationary solutions to a chemotaxis-consumption model with realistic boundary conditions

Marcel Braukhoff, Johannes Lankeit

Previous studies of chemotaxis models with consumption of the chemoattractant (with or without fluid) have not been successful in explaining pattern formation even in the simplest…

Semiconductor Boltzmann-Dirac-Benney equation with BGK-type collision operator: existence of solutions vs. ill-posedness

Marcel Braukhoff

A semiconductor Boltzmann equation with a non-linear BGK-type collision operator is analyzed for a cloud of ultracold atoms in an optical lattice: \[ \partial_t f + \nabla_pε(p)\cd…

Energy-transport systems for optical lattices: derivation, analysis, simulation

Marcel Braukhoff, Ansgar Jüngel

Energy-transport equations for the transport of fermions in optical lattices are formally derived from a Boltzmann transport equation with a periodic lattice potential in the diffu…
