Birational conjugacies between endomorphisms on the projective plane

Algebraic Geometry 2025-09-23 v3 Dynamical Systems

Abstract

We proved that, in characteristic 0, if two dominant endomorphisms of the projective plane of degree at least 2 are conjugate by some birational transformation, then they are conjugate by an automorphism. We also gave counterexamples in positive characteristic.
