Exponential convergence to equilibrium for coupled systems of nonlinear degenerate drift diffusion equations

Lisa Beck, Daniel Matthes, Martina Zizza

We study the existence and long-time asymptotics of weak solutions to a system of two nonlinear drift-diffusion equations that has a gradient flow structure in the Wasserstein dist…

Boundary regularity for elliptic systems under a natural growth condition

Lisa Beck

We consider weak solutions $u \in u_{0} + W_{0}^{1, 2} (Ω, R^{N}) \cap L^{\infty} (Ω, R^{N})$ of second order nonlinear elliptic systems of the type $- d i v a (\cdot, u, D u) = b (\cdot, u, D u)$ in…
