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…

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…

Certifying nontriviality of Ceresa classes of curves

Jordan Ellenberg, Adam Logan, Padmavathi Srinivasan

The Ceresa cycle is a canonical algebraic $1$ -cycle on the Jacobian of an algebraic curve. We construct an algorithm which, given a curve over a number field, often provides a cert…
