Continuity of Lyapunov exponents for polynomial automorphisms of $\mathbb{C}^2$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/115531We prove two continuity theorems for the Lyapunov exponents of the maximal entropy measure of polynomial automorphisms of $\mathbb{C}^2$. The first continuity result holds for any family of polynomial automorphisms of constant dynamical degree. The second result is the continuity of the upper exponent for families degenerating to a 1-dimensional map.Dynamical SystemsComplex Variables37f45;37f10Continuity of Lyapunov exponents for polynomial automorphisms of $\mathbb{C}^2$text
