摘要: 该文运用代数体函数的球面特征函数作为比较函数, 定义了代数体函数的 T 方向, 证明了平面上的代数体至少存在一条 T 方向,其例外值的个数至多为2+[δx] ≤ 2 ν.

关键词: T 方向, 特征函数, 比较函数

Abstract: In this paper, by using spherical characteristic function T(r, w), the authors define and establish the existence of a new singular direction for the algebroidal function w, namely a T direction, for which the characteristic function T(r, w) is used as a comparison function. Moreover, the authors prove that the number of exceptional values is at most 2+[δx] ≤ 2 ν.

Key words: T direction, Algebroidal function, Characteristic function
