扩张半流素轨道定理的误差项

The error term of the prime orbit theorem for expanding semiflows

Masato Tsujii

摘要:

考虑圆上角乘映射的悬浮半流,研究其周期轨道的周期分布。在屋顶函数的一般条件下,给出了周期为$\le T$的素周期轨道个数$π(T)$的渐近公式。对于任意小的$\varepsilon>0$,误差项至少由\[ \exp((1-\frac{1}{4\lceil χ_{\max}/h_{\mathrm{top}}\rceil}+\varepsilon) h_{\top} T)\qquad {in the limit $T\to \infty$} \]有界,其中$h_{\mathrm{top}}$和$χ_{\max}$分别是半流的拓扑熵和最大李雅普诺夫指数。

英文摘要:

We consider suspension semiflows of an angle multiplying map on the circle and study the distributions of periods of their periodic orbits. Under generic conditions on the roof function, we give an asymptotic formula on the number $π(T)$ of prime periodic orbits with period $\le T$. The error term is bounded, at least, by \[ \exp((1-\frac{1}{4\lceil χ_{\max}/h_{\mathrm{top}}\rceil}+\varepsilon) h_{\top} T)\qquad {in the limit $T\to \infty$} \] for arbitrarily small $\varepsilon>0$, where $h_{\mathrm{top}}$ and $χ_{\max}$ are respectively the topological entropy and the maximal Lyapunov exponent of the semiflow.
