Log Adjunction: effectiveness and positivity
Abstract
This is a first instalment of much larger work about relations between birational geometry and moduli of triples. The extraction of work is mainly related to Theorem 6. It is a weak version of Kawamata's Conjecture 1 and an important technical step toward semiampleness of moduli part of adjunction. To prove Theorem 6, we use relative analogues of brepresentations. The proof here is rather complete except for bmobile property used in Corollary 1.
