The Tate conjecture for surfaces of geometric genus one -- embracing singularities

Abstract

In this article, we aim to largely complete the program of proving the Tate conjecture for surfaces of geometric genus one, by introducing techniques to analyze those surfaces whose "natural models" are singular. As an application, we show that every elliptic curve of height one over a global function field of genus one and characteristic $p\ge 11$ satisfies the Birch--Swinnerton-Dyer conjecture.
