Refined Humbert invariants and subvarieties of $\Ac_2(\C)$: the rank 3 case

Elisa Lorenzo García, Christophe Ritzenthaler

Over the complex field, we show that the principally polarised abelian surfaces with a given refined Humbert invariant of rank 3 are all Galois conjugated.

Computing Invariants of Artin-Schreier Curves

Juanita Duque-Rosero, Elisa Lorenzo García, Beth Malmskog +1

We present an algorithmic framework for computing generators for the ring of invariants of an Artin-Schreier curve. We give explicit invariants for almost all Artin-Schreier curves…

Refinements of Katz-Sarnak theory for the number of points on curves over finite fields

Jonas Bergström, Everett W. Howe, Elisa Lorenzo García +1

This paper goes beyond Katz-Sarnak theory on the distribution of curves over finite fields according to their number of rational points, theoretically, experimentally and conjectur…

Determining the primes of bad reduction of CM curves of genus 3

Sorina Ionica, Pinar Kiliçer, Kristin Lauter +3

In this paper we introduce a new problem called the Isogenous Embedding Problem (IEP). The existence of solutions to this problem is related to the primes of bad reduction of CM cu…

Lower bounds on the maximal number of rational points on curves over finite fields

Jonas Bergström, Everett W. Howe, Elisa Lorenzo García +1

For a given genus , we give lower bounds for the maximal number of rational points on a smooth projective absolutely irreducible curve of genus over .…

Decomposing Jacobians via Galois covers

Davide Lombardo, Elisa Lorenzo García, Christophe Ritzenthaler +1

Let be a (possibly ramified) cover between two algebraic curves of positive genus. We develop tools that may identify the Prym variety of , up to isogeny, a…
