Compressibility and volume variations due to composition in multicomponent fluids
Pierre-Etienne Druet
For single components fluids, vanishing isothermal compressibility implies that the mass density is constant, but the same conclusion is unknown for multicomponent fluids. Here the…
The initial acceleration of a buoyant spherical bubble revisited
Dieter Bothe, Jun Liu, Pierre-Etienne Druet +3
An analytical derivation of the buoyancy-induced initial acceleration of a spherical gas bubble in a host liquid is presented. The theory makes no assumptions further than applying…
Persistence exponents via perturbation theory: MA(1)-processes
Frank Aurzada, Dieter Bothe, Pierre-Étienne Druet +2
For the moving average process , , where and is an i.i.d. sequence of normally distributed random variables, we…
Gradient and Hessian regularity in elliptic transmission problems near a point cusp
Dieter Bothe, Pierre-Etienne Druet, Robert Haller
We consider elliptic transmission problems in several space dimensions near an interface which is diffeomorphic to an axisymmetric reference-interface with a singular poi…
A regularity result for quasilinear elliptic systems with an equation of energy-type
Pierre-Etienne Druet
We study the continuity of weak solutions for quasilinear elliptic systems with source terms of critical growth arising from a transport-energy structure. The latter occurs frequen…
Hyperbolic-parabolic normal form and local classical solutions for cross-diffusion systems with incomplete diffusion
Pierre-Étienne Druet, Katharina Hopf, Ansgar Jüngel
We investigate degenerate cross-diffusion equations with a rank-deficient diffusion matrix that are considered to model populations which move as to avoid spatial crowding and have…
