Non-uniqueness of mild solutions to supercritical heat equations
Irfan Glogić, Martina Hofmanová, Theresa Lange +1
We consider the focusing power nonlinearity heat equation \begin{equation}\label{Eq:Heat_abstract}\tag{NLH} \partial_t u -Δu = |u|^{p-1}u, \quad p>1, \end{equation} in dimensions $…

Non-uniqueness of Leray--Hopf solutions for the fractional Navier--Stokes equations perturbed by transport noise
Theresa Lange, Marco Rehmeier, Andre Schenke
For the fractional Navier--Stokes equations perturbed by transport noise, we prove the existence of infinitely many Hölder continuous analytically weak, probabilistically stro…

On convex integration solutions to the surface quasi-geostrophic equation driven by generic additive noise
Florian Bechtold, Theresa Lange, Jörn Wichmann
We study the surface quasi-geostrophic equation driven by a generic additive noise process . By means of convex integration techniques, we establish existence of weak solutions…
