无不变密度的复映射

Complex maps without invariant densities

Henk Bruin, Mike Todd

摘要:

考虑复多项式$f(z) = z^\ell+c_1$对$\ell \in 2\N$和$c_1 \in \R$,找到了$\ell$的一些组合类型和值,使得在朱利亚集上不存在等价于共形测度的不变概率测度.当$\ell$足够大时,这适用于特定的Fibonacci样和Feigenbaum组合类型,也适用于任何临界阶的一类“长分支”映射。

英文摘要:

We consider complex polynomials $f(z) = z^\ell+c_1$ for $\ell \in 2\N$ and $c_1 \in \R$, and find some combinatorial types and values of $\ell$ such that there is no invariant probability measure equivalent to conformal measure on the Julia set. This holds for particular Fibonacci-like and Feigenbaum combinatorial types when $\ell$ sufficiently large and also for a class of `long-branched' maps of any critical order.
