Dinâmica de Aplicações Cohomologicamente Hiperbólicas

Abstract

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.
