Stabilization indices of potentially Mumford curves

Andrew Obus, Daniele Turchetti

Let $X$ be a smooth projective curve over a complete discretely valued field $K$ . Let $L / K$ be the minimal extension such that $X \times_{K} L$ has a semi-stable model, and write $e(…

Minimal regular normal crossings models of superelliptic curves

Andrew Obus, Padmavathi Srinivasan

Let $K$ be a complete discretely valued field with perfect residue field $k$ . If $X \to P_{K}^{1}$ is a $Z / d$ -cover with $char k ∤ d$ , we compute the mini…
