Fujita's very ampleness conjecture for singular toric varieties

Pages. 447-459
Abstract We present a self-contained combinatorial approach to Fujita's conjectures in the toric case. Our main new result is a generalization of Fujita's very ampleness conjecture for toric varieties with arbitrary singularities. In an appendix, we use similar methods to give a new proof of an analogous toric generalization of Fujita's freeness conjecture due to Fujino. 1. Introduction 2. Preliminaries 3.
