摘要 本文研究了整函数的唯一性,证明了如下结果:设p(z)为n_1多项式,f(z)和g(x)是两个超越亚纯函数,n≥max{6,n_1}是一个正整数,如果f^n(z)f′(z),g^n(z)g′(z)分担多项式p(z)CM,则f(z)=c_1e^(c∫p(z)dz),g(z)=c_2e^(-c∫p(z)dz),这里c_1,c_2和c是三个常数且满足(c_1c_2)^(n+1)c^2=-1;或者f(z)≡tg(z),其中t是一个常数且满足t^(n+1)=1. In this paper, we study the uniqueness of entire functions and prove the following result: Let f(z) and g(z) be two transcendental entire functions, p(z) a polynomial of degree n1; n 〉. max{6,n1} a positive integer. If f^n(z)f′(z) and g^n(z)g′(z) share p(z) CM, then either f(z) = c1 e^c ∫ p(z)dz,g(z) = c2e^-c ∫p(z)d^z, where c1, c2 and c are three constants satisfying (c1c2)^n+1c^2 = -1; or f(z) ≡ tg(z) for a constant t such that t^n+x = 1.
