Weak–strong uniqueness for the Navier–Stokes equation for two fluids with surface tension

J Fischer, S Hensel - Archive for Rational Mechanics and Analysis, 2020 - Springer
In the present work, we consider the evolution of two fluids separated by a sharp interface in
the presence of surface tension—like, for example, the evolution of oil bubbles in water. Our …

A brief overview of existence results and decay time estimates for a mathematical modeling of scintillating crystals

F Daví - Mathematical Methods in the Applied Sciences, 2021 - Wiley Online Library
Inorganic scintillating crystals can be modelled as continua with microstructure. For rigid and
isothermal crystals, the evolution of charge carriers becomes in this way described by a …

Uniqueness of strong solutions and weak–strong stability in a system of cross-diffusion equations

J Berendsen, M Burger, V Ehrlacher… - Journal of Evolution …, 2020 - Springer
Proving the uniqueness of solutions to multi-species cross-diffusion systems is a difficult task
in the general case, and there exist very few results in this direction. In this work, we study a …

Global existence analysis of energy-reaction-diffusion systems

J Fischer, K Hopf, M Kniely, A Mielke - SIAM Journal on Mathematical Analysis, 2022 - SIAM
We establish global-in-time existence results for thermodynamically consistent reaction-
