Factorization of anticanonical maps of Fano type varieties

Algebraic Geometry 2014-12-30 v2

Abstract

The purpose of the present paper is to generalize Sakai's work on anticanonical models of rational surfaces to varieties of Fano type. We first prove a characterization of Fano type varieties using the singularities of anticanonical models. Secondly, we study the decomposition of the anticanonical map using the KXK_X-minimal model program.
