摘 要: 本文利用精简计数函数给出了微分多项式af^2(f^((k)))~n-1,n≥2的定量估计不等式,设f为超越亚纯函数,n,k为正整数,其中a(z)≠0为f(z)的小函数满足T(r,a)=S(r,f). In this paper, a quantitative estimate of the value distribution of the differential polynomials af2(f(k))n-1,n≥2is obtained by the reduced counting function, where n,k are positive integer,a(z)≠0为f(z)is the small function of f(z) which satisfies T(r,a) = S(r,f).
