Large-time asymptotics for degenerate cross-diffusion population models with volume filling

Xiuqing Chen, Ansgar Jüngel, Xi Lin +1

The large-time asymptotics of the solutions to a class of degenerate parabolic cross-diffusion systems is analyzed. The equations model the interaction of an arbitrary number of po…

Analysis of a Poisson-Nernst-Planck-Fermi system for charge transport in ion channels

Ansgar Jüngel, Annamaria Massimini

A modified Poisson-Nernst-Planck system in a bounded domain with mixed Dirichlet-Neumann boundary conditions is analyzed. It describes the concentrations of ions immersed in a pola…

Global weak solutions for a nonlocal multispecies Fokker-Planck-Landau system

Jingwei Hu, Ansgar Jüngel, Nicola Zamponi

The global-in-time existence of weak solutions to a spatially homogeneous multispecies Fokker-Planck-Landau system for plasmas in the three-dimensional whole space is shown. The Fo…

Existence analysis for a reaction-diffusion Cahn-Hilliard-type system with degenerate mobility and singular potential modeling biofilm growth

Christoph Helmer, Ansgar Jüngel

The global existence of bounded weak solutions to a diffusion system modeling biofilm growth is proven. The equations consist of a reaction-diffusion equation for the substrate con…
