核心概念
本文證明了存在一個至少包含 13 個元素的有限集 S,使得如果兩個非常數亞純函數 f 和 g 滿足 Ef(S, 1) = Eg(S, 1),則 f ≡ g。
統計資料
n ≥ 13 (對於亞純函數)
n ≥ 8 (對於整函數)
引述
"Two meromorphic functions f and g are said to share the set S ⊂ C ∪{∞} with weight l ∈N ∪{0} ∪{∞}, if Ef(S, l) = Eg(S, l)."
"In this paper, we improve and supplement the result of L. W. Liao and C. C. Yang (On the cardinality of the unique range sets for meromorphic and entire functions, Indian J. Pure appl. Math., 31 (2000), no. 4, 431-440) by showing that there exist a finite set S with cardinality ≥13 such that Ef(S, 1) = Eg(S, 1) implies f ≡g."
