Abstract:
In this paper, we study the deficient relation of some transcendental entire functions. If fj(z)(j=1, 2, …, p) be transcendental entire functions, and let aj(j=1, 2, …, p) be nonzero finite complex numbers. If ∑pj=1ajfj(z)≡1, then ∑pj=1δp-1(0, fj)≤p-1, where δp-1(0, fj)=1-lim-r→∞(Np-1(r, 1/fj))/(T(r, fj))(j=1, 2, …, p). The result improves a result of Niino and Ozawa. Meanwhile we give some applications of our result.
讨论了一些超越整函数亏量间的关系.如果f1(z), f2(z), …, fp(z)都是超越整函数, a1, a2, …, ap 都是非零有限复数, 并且∑pj=1ajfj≡1, 则∑pj=1δ(0, fj)≤p-1.这里δ(
