Fujita's Conjecture and Frobenius amplitude
arXiv:math/0606406 · doi:10.1353/ajm.0.0015, 10.1353/ajm.2019.0039
Abstract
We prove a version of Fujita's Conjecture in arbitrary characteristic, generalizing results of K.E. Smith. Our methods use the Frobenius morphism, but avoid tight closure theory. We also obtain versions of Fujita's Conjecture for coherent sheaves with certain ampleness properties.
