Carathéodory's theorem

Carathéodory's theorem

In mathematics, Carathéodory's theorem may refer to one of a number of results of Constantin Carathéodory:

* Carathéodory's theorem (convex hull) about the convex hulls of sets in Euclidean space
*Carathéodory's theorem (measure theory) about outer measures in measure theory
*Carathéodory's extension theorem about the extension of a measure.
*Carathéodory's theorem (conformal mapping)
*Borel–Carathéodory theorem, about the boundedness of a complex analytic function.
