Vojta's abc Conjecture for algebraic tori and applications over function fields

Number Theory 2023-10-20 v3

Abstract

We prove Vojta's generalized abc conjecture for algebraic tori over function fields with exceptional sets that can be determined effectively. Additionally, we establish a version of the conjecture for toric varieties. As an application, we investigate the Lang-Vojta Conjecture for varieties of log general type that are ramified covers of Gmn\mathbb G_m^n over function fields. In particular, we consider the case of PnD \mathbb P^n\setminus D, where DD is an algebraic curve over a function field in Pn\mathbb P^n with n+1n+1 irreducible components and degDn+2\deg D\ge n+2. Our methods also apply to the complex situation, enabling us to find explicit exceptional sets for the corresponding case of Vojta's general abc conjecture (complex version) and the Green-Griffith-Lang conjecture.
