On p-power freeness in positive characteristic

Algebraic Geometry 2020-03-13 v2

Abstract

In this note, we study base point freeness up to taking p-power, which we will call p-power freeness. We first establish some criteria for p-power freeness as analogues of criteria for semi-ampleness. We then apply these results to three-dimensional birational geometry.
