摘要

如果一个衍射保留了至少一个零 Lyapunov 指数的遍历度量,那么它就是非均匀部分双曲的。我们证明,如果 C1-smooth ℤd-action 的一个生成器是 C1+α (α > 0) 非均匀部分双曲的,那么它就具有准阴影性质。

Quasi-shadowing for ℤd-actions

A diffeomorphism is non-uniformly partially hyperbolic if it preserves an ergodic measure with at least one zero Lyapunov exponent. We prove that a C1-smooth ℤd-action has the quasi-shadowing property if one of the generators is C1+α (α > 0) non-uniformly partially hyperbolic.
