Sources of log canonical centers

Algebraic Geometry 2012-11-15 v3

Abstract

We define the "source" and the "spring" of a log canonical center and use them to solve several problems in higher-codimension adjunction. The main application is to the construction of semi log canonical pairs. Version 2: References updated. Version 3: Many small changes.
