Infinitely many primes of basic reduction for some abelian fourfolds

Wanlin Li, Elena Mantovan, Rachel Pries +1

If $E$ is an elliptic curve, defined over $Q$ or a number field having at least one real embedding, then Elkies proved that $E$ has supersingular reduction at infinitely m…

Positive density of primes of ordinary reduction for abelian varieties of simple signature

Victoria Cantoral FarfÃ¡n, Wanlin Li, Elena Mantovan +2

By a result of Serre, if $A$ is an elliptic curve without CM defined over a number field $L$ , then the set of primes of $L$ for which $A$ has ordinary reduction has density $1$ . Ka…

On $ℓ$ -torsion in degree $ℓ$ superelliptic Jacobians over $F_{q}$

Wanlin Li, Jonathan Love, Eric Stubley

We study the $ℓ$ -torsion subgroup in Jacobians of curves of the form $y^{ℓ} = f (x)$ for irreducible $f (x)$ over a finite field $F_{q}$ of characteristic $p \neq \ell…
