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…

Classical forms of weight one in ordinary families

Eric Stubley

We develop a new strategy for studying low weight specializations of $p$ -adic families of ordinary modular forms. In the elliptic case, we give a new proof of a result of Ghate--Va…

Class groups of Kummer extensions via cup products in Galois cohomology

Karl Schaefer, Eric Stubley

We use Galois cohomology to study the $p$ -rank of the class group of $Q (N^{1/ p})$ , where $N \equiv 1 mod p$ is prime. We prove a partial converse to a theorem of Calega…
