On log minimal models and Zariski decompositions II
arXiv:1302.4015
Abstract
We continue our study of the relation between log minimal models and various types of Zariski decompositions. Let be a projective log canonical pair. We will show that has a log minimal model if either birationally has a Nakayama-Zariski decomposition with nef positive part, or that is big and birationally it has a Fujita or CKM Zariski decomposition. Along the way we introduce polarized pairs where is a usual projective pair and is nef, and study the birational geometry of such pairs.
