An alternative approach to solenoidal Lipschitz truncation
Stefan Schiffer
In this work, a new approach to obtain a solenoidal Lipschitz truncation is presented. More precisely, the goal of the truncation is to modify a function $u \in W^{1,p}(\mathbb{R}^…

A data-driven approach to viscous fluid mechanics -- the stationary case
Christina Lienstromberg, Stefan Schiffer, Richard Schubert
We introduce a data-driven approach to the modelling and analysis of viscous fluid mechanics. Instead of including constitutive laws for the fluid's viscosity in the mathematical m…

Natural annihilators and operators of constant rank over
Franz Gmeineder, Stefan Schiffer
Even if the Fourier symbols of two constant rank differential operators have the same nullspace for each non-trivial phase space variable, the nullspaces of those differential oper…
