Let \({\mathcal {F}}\) be a family of holomorphic functions on a domain D, and let \(h(\not \equiv 0)\) be a holomorphic function on D. If every \(f\in {\mathcal {F}}\), \(f(z)=0\Rightarrow |f'(z)|\le |h(z)|\), and \(f'(z)\ne h(z)\), then \({\mathcal {F}}\) is normal on D.

全纯函数族的标准
假设\({\ mathcal {F}} \)是域D上的一族全纯函数,而\(h(\ not \ equiv 0)\)是D上的一全纯函数。如果每个\(f \ in {\ mathcal {F}} \\),\(f(z)= 0 \ Rightarrow | f'(z)| \ le | h(z)| \)和\(f' (z)\ ne h(z)\),则\({\ mathcal {F}} \)在D上是正常的。
