On twisted Kawamata's semi-positivity and finite generation of generalized canonical rings

arXiv:2404.07401

Abstract

We give a twisted version of the Kawamata semi-positivity theorem by the -line bundle with a vanishing Lelong number at every point. Moreover, we apply the result to the finite generation problem for canonical rings of Birkar's generalized pairs.
