On the typical rank of elliptic curves over ${\mathbb Q}(T)$

Number Theory 2022-03-30 v2

Abstract

We give upper bounds for the number of rational elliptic surfaces in some families having positive rank, obtaining in particular that these form a subset of density zero. This confirms Cowan's conjecture (arXiv:2009.08622v2) in the case m,n2m,n\leq2.
