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]≤2v.
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] ≤ 2v.
