Montel's theorem
From Wikipedia, the free encyclopedia
In complex analysis, an area of mathematics, Montel's theorem, named after Paul Montel, is an important theorem about sets (also called families) of holomorphic functions.
[edit] Montel's theorem
Given a family F of holomorphic functions defined on an open subset D of the complex numbers C, then F is a normal family if and only if F is locally bounded.
The key part of this theorem can be reformulated as follows. Any locally bounded sequence of holomorphic functions fn defined on D has a subsequence which converges compactly to a holomorphic function f.
