我们证明了存在一个有限增长阶的双曲完整函数f,使得其双曲维数,即轨道有界的f的Julia集合中点的集合的Hausdorff维数,等于2。这与有理数情况相反,在有理数情况下,双曲映射的Julia集必须具有小于2的Hausdorff维数,并且与所有已知的显式双曲完整函数的情况相反。
We show that there exists a hyperbolic entire function f of finite order of growth such that the hyperbolic dimension, that is, the Hausdorff dimension of the set of points in the Julia set of f whose orbit is bounded, is equal to 2. This is in contrast to the rational case, where the Julia set of a hyperbolic map must have Hausdorff dimension less than 2, and to the case of all known explicit hyperbolic entire functions.
