Boundedness results for families of non-canonically polarized projective varieties

Abstract

We prove that, over a smooth quasi-projective curve, the set of non-isotrivial, smooth and projective families of polarized varieties with a fixed Hilbert polynomial and semi-ample canonical bundle is bounded. This extends the boundedness results of Arakelov, Parshin, and Kovács--Lieblich beyond the canonically polarized case.
