余维为1的奇异双曲流的自适应算法

Adapted Metrics for Codimension one Singular Hyperbolic Flows

Luciana Salgado, Vinicius Coelho

摘要:

对于$m$ -流形$M$上的$C^1$向量场$X$的部分双曲分裂,基于向量积的思想,得到了$E$是否为一维子空间的奇异双曲性.本文证明了奇异双曲集具有部分双曲分裂$T_ΓM = E \oplus F$的适应度量的存在性,其中$F$是体积膨胀子丛,$E$是一致收缩的一维子丛.这些结果推广了第一作者和V. Araújo的结果。

英文摘要:

For a partially hyperbolic splitting a $C^1$ vector field $X$ on a $m$-manifold $M$, we obtain singular hyperbolicity whether $E$ is one-dimensional subspace, based on the idea of cross products. We show the existence of adapted metrics for singular hyperbolic set if it has a partially hyperbolic splitting $T_ΓM = E \oplus F$, where $F$ is a volume expanding subbundle, $E$ is an uniformly contracted and one-dimensional subbundle. Theses results extend previous ones from the first author and V. Araújo.
