ACC for log canonical thresholds and termination of log flips

arXiv:math/0502116

Abstract

We prove that the ascending chain condition (ACC) for log canonical (lc) thresholds in dimension and Special Termination in dimension imply the termination of any sequence of log flips starting with a -dimensional lc pair of nonnegative Kodaira dimension. In particular, in characteristic zero, the latter termination in dimension 4 follows from Alexeev-Borisov's conjecture in dimension 3.
