摘要:

研究了具有跟踪性质的动力系统中的$Φ$ -非正则集(Birkhoff平均发散的点集)的性质.利用链回归类上的熵估计了$Φ$ -不正则集的拓扑熵,证明了全熵的$Φ$ -不正则集是典型的.我们还考虑了$Φ$ -水平集(Birkhoff平均值在指定区间内的点集),将它们所携带的熵与某些遍历测度的熵联系起来。最后,我们研究了水平集关于参考测度的大偏差问题。

英文摘要:

We study the properties of $Φ$-irregular sets (sets of points for which the Birkhoff average diverges) in dynamical systems with the shadowing property. We estimate the topological entropy of $Φ$-irregular set in terms of entropy on chain recurrent classes and prove that $Φ$-irregular sets of full entropy are typical. We also consider $Φ$-level sets (sets of points whose Birkhoff average is in a specified interval), relating entropy they carry with the entropy of some ergodic measures. Finally, we study the problem of large deviations considering the level sets with respect to reference measures.
