Findings

Exponential convergence of normalized inverse images of smooth forms.

Convergence occurs outside the invariant subset E.

Abstract

In this paper, we prove that for a given surjective holomorphic endomorphism $f$ of a compact K\"ahler manifold $X$ and for some integer $p$ with $1\le p\le k$, there exists a proper invariant analytic subset $E$ for $f$ such that if $S$ is smooth in a neighborhood of $E$, the sequence $d_p^{-n}(f^n)^*(S-\alpha_S)$ converges to $0$ exponentially fast in the sense of currents where $d_p$ denotes the dynamical degree of order $p$ and $\alpha_S$ is a closed smooth form in the de Rham cohomology class of $S$.
