摘要
本文对阶λ<1/2的整函数的奇异方向的分布作了讨论。主要结论:若0<λ=μ<1/2,则从原点出发的任意射线△(θ),或者△(θ)是f(z)的Julia方向或者存在某个包含△(θ)的扇形域S使lim |z|→∞z∈s loglog|f(z)
In this paper the auther researched the distribution of Julia directions of entire function of order less than 1/2. Theorem: Let f(z) be entire function of order λ and lower order μ: 0<λ=μ<1/2. Then for any θ: 0≤θ<2π, either Δ(θ) is Julia direction of f(z)or there is a sector S containing Δ(θ) such that lim z→∞ z∈s log log|f(z)|/log|z|=λ
