Dynamical Iitaka theory on Fano contractions (2506.16057v1)

Published 19 Jun 2025 in math.AG, math.DS, and math.NT

Abstract: We give several structure theorems for certain surjective endomorphisms on Mori fibre spaces, based on the dynamical Iitaka fibration of the ramification divisor. As an application, we prove the Kawaguchi-Silverman conjecture for projective bundles over abelian varieties or smooth projective varieties of Picard number one.
