Covers of curves, Ceresa cycles, and Unlikely intersections

Tejasi Bhatnagar, Sheela Devadas, Toren D'Nelly-Warady +1

Fix a smooth, projective, geometrically integral curve $C$ of genus $g \geq 2$ over a characteristic zero field. We prove that the Ceresa cycle $Cer (C)$ of a v…

p-adic adelic metrics and Quadratic Chabauty I

Amnon Besser, J. Steffen MÃ¼ller, Padmavathi Srinivasan

We give a new construction of $p$ -adic heights on varieties over number fields using $p$ -adic Arakelov theory. In analogy with Zhang's construction of real-valued heights in terms…

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…

Curve equations from expansions of 1-forms at a nonrational point

Raymond van Bommel, Edgar Costa, Bjorn Poonen +1

We exhibit an algorithm to compute equations of an algebraic curve over a computable characteristic 0 field from the power series expansions of its regular 1-forms at a nonrational…
