Bjorn Poonen asked whether there exists a polynomial giving a surjection $\mathbb{Z} \times \mathbb{Z} \to \mathbb{N}$. We answer this question in the negative, conditional on a conjecture of Vojta. More precisely, we show that if such a function exi

What mathematician would you interview if you had the chance? As part of a seminar at Wellesley College called Explaining Mathematics, students arrange, conduct, and produce an interview with a mat...

Our goal is to introduce Drinfeld modules and to explain their application to explicit class field theory.

Let G$G$ be a subgroup of the symmetric group Sn$S_n$. If the proportion of fixed-point-free elements in G$G$ (or a coset) equals the proportion of fixed-point-free elements in Sn$S_n$, then G=Sn$G=S_n$. The analogue for An$A_n$ holds if n > 7$n \geq

We introduce a common generalization of essentially all known methods for explicit computation of Selmer groups, which are used to bound the ranks of abelian varieties over global fields. We also simplify and extend the proofs relating what is comput

Refining a theorem of Zarhin, we prove that given a $g$-dimensional abelian variety $X$ and an endomorphism $u$ of $X$, there exists a matrix $A \in \operatorname{M}_{2g}(\mathbb{Z})$ such that each Tate module $T_\ell X$ has a $\mathbb{Z}_\ell$-basi
