Dinâmica de Aplicações Cohomologicamente Hiperbólicas

Let $f:X \longrightarrow X $ be a Cohomological Hyperbolic Mapping of a complex compact connected Kähler manifold with $ dim_{\mathbb{C}}(X)=k \ge 1$. We want to study the dynamics of such mapping from a probabilistic point of view, that is, we will try to describe the asymptotic behavior of the orbit $ O_{f} (x) = \{f^{n} (x), n \in \mathbb{N}$ or $\mathbb{Z}\}$ of a generic point. To do this, using pluripotential methods, we will construct a natural invariant canonical probability measure of maximum entropy $ μ_{f} $ such that $ λ_{\max}^{-n}(f^{n})^{\star}Θ\longrightarrow μ_{f} $ for each smooth probability measure $Θ$ in $X$ with $ λ_{k} := \limsup_{n\longrightarrow \infty} \{||(f^{n})^{\star}||^{\frac{1}{n}}\} $ the number of pre-images of a generic point of $X $ by $f $. Then we will study the main stochastic properties of $ μ_{f}$ and show, if possible, that $ μ_{f}$ is a measure of equilibrium, smooth, hyperbolic, ergodic, mixing, $\mathbb{K} $ -mixing, exponential-mixing, moderate and the only measure of maximum entropy, absolutely continuous with respect to the LEBESGUE measure and to the HAUSDORFF measure under certain hypotheses. On the other hand, we will introduce the concept of Perfect and $\mathbb{K} $-Perfect Measure and indeed show that $ μ_{f}$ is $\mathbb{K} $-Perfect.

Conceitos Fundamentais e Métodos Pluripotenciais para Aplicações Cohomologicamente Expansíveis

In this text, we recall some basics and results about complex geometry and currents in the complex scenario. Most of the results are classic and their evidence is not given here. On the other hand, we describe in detail some notions to help the reader who is unfamiliar with complex geometry or currents. The main references for abstract current theory are [Che03] [dR84] [Fed69] [Sch66] [War71]. The reader will find in [JP] [Gun90] [Hor83] [Lel68] [Nar66] the basics of chains in complex varieties. We also refer to [JP] [PA78] [Huy05] [Voi02] for Kähler's compact variety theory

Graus Dinâmicos e Cohomológicos em Variedades Abelianas

We prove that for an endomorphism $f$ of an abelian manifold defined over an algebraically closed field of arbitrary characteristic, $ χ_ {2q} (f) = λ_q (f) $. Note that this paper is based on recent results due to Fei Hu \cite{Hu19}, \cite{Hu-cndd}, \cite{Hu-Tits} e Truong \cite {Truong1611}.
