Unicity theorems for entire functions concerning four small functions

摘要

References(7) This paper studies the problem of uniqueness of entire functions concerning four small functions and shows that if two entire functions f and g satisfy ar{E}(aj, k, f)=ar{E}(aj, k, g) for j=1, 2, 3, 4, where aj are four distinct small functions with respect to f and g, and k is a positive integer or ∞ with k≥8, then f≡g.
