Forschungsseminar Algebraische Geometrie

New instances of Vojta’s Main Conjecture via Newton-Okounkov bodies and K-(in)stability

Organizer: D. Greb

The goal of the seminar is to understand the relation between Nevanlinna theory and Vojta’s conjecture in Diophantine Geometry on the one side and notions of birational geometry related to linear series and K-stability of Fano varieties on the other side, based on the recent paper arXiv:1901.07942 of Grieve.

Recommendation: For an in-depth introduction to Vojta’s conjecture, the contribution of Vojta to the following volume of lecture notes (which you can download freely if you access it via a UDE-IP-address) is highly recommended: Vojta-survey
