Vojta's abc conjecture for algebraic tori and applications over function fields
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 over function fields. In particular, we consider the case of , where D is a hypersurface over a function field in with irreducible components and . 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-Griffiths-Lang conjecture.
