Semistable reduction of smooth quartics
Max Schwegele, Kletus Stern, Stefan Wewers
We develop a method for computing stable reduction of smooth plane quartics over discretely valued fields, including residue characteristic p=2. The method uses the GIT-semistable…

Models of hypersurfaces and Bruhat-Tits buildings
Kletus Stern, Stefan Wewers
We propose a new approach to constructing semistable integral models of hypersurfaces over a discretely valued complete field K. For each stable hypersurface X over K we define a c…
