摘要:
本文研究有穷级整函数 与其差分算子 或移位算子 计数分担一小函数 的唯一性问题。得到两个重要结论:如果 和 计数分担 ,则 。如果 和 计数分担 ,则 或 。这些结论推广了李昇和高宗升在[1]中的结论。
In this paper, we investigate an entire function of finite order share a small function with its difference and shift. Two theorems will be got, that is, if and share CM (counting multiplies), then ; if and share CM, then or . The results we obtain improve some known results of Li Sheng and Gao Zongsheng in [1].
