在平面上留下一个非常亚纯函数和一个非常椭圆函数。我们证明了如果所有的零都是除有限多个以外的多个,并且T(r, h) = 0 {T(r, f)} asr→∞,则f ' =h有无穷多个解(包括极点)。
Letfbe a nonconstant meromorphic function in the plane andhbe a nonconstant elliptic function. We show that if all zeros offare multiple except finitely many andT(r, h) =o{T(r, f)} asr→∞, thenf′ =hhas infinitely many solutions (including poles).
