Explicit local stable resolution of cusps
Stefan Wewers
This article gives an explicit local stable resolution of cusps on GIT-stable plane quartic models. More generally, we consider a smoothing of an ordinary plane cusp over a complet…
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…
Integral differential forms for superelliptic curves
Sabrina Kunzweiler, Stefan Wewers
Given a superelliptic curve over a local field , we describe the theoretical background and an implementation of a new algorithm for computing the $\mathcal{O…
