Projectivity of the moduli space of stable log-varieties and subadditvity of log-Kodaira dimension

Abstract

We prove a strengthening of Kollár's Ampleness Lemma and use it to prove that any proper coarse moduli space of stable log-varieties of general type is projective. We also prove subadditivity of log-Kodaira dimension for fiber spaces whose general fiber is of log general type.
