Rational nef and anti-nef polytopes are not uniform

Algebraic Geometry 2021-03-30 v1

Abstract

We give two examples which show that rational nef and anti-nef polytopes are not uniform even for klt surface pairs, answering a question of Chen-Han. We also show that rational nef polytopes are uniform when the Cartier indices are uniformly bounded.
