Caratheodory's theorem

WebThe Carathéodory derivative gives a better motivation for the linearity of the derivative however the Fréchet does give a better geometric interpretation. I'm not trying to argue that one is better than the other because that's a useless argument. But you've completely missed my point.

Carathéodory's theorem in 2 dimensions states that we can construct a triangle consisting of points from P that encloses any point in the convex hull of P. For example, let P = {(0,0), (0,1), (1,0), (1,1)}. The convex hull of this set is a square. Let x = (1/4, 1/4) in the convex hull of P. We can then construct a set … See more Carathéodory's theorem is a theorem in convex geometry.

Borel-Caratheodory Lemma and Its Application Travor

In measure theory, Carathéodory's extension theorem (named after the mathematician Constantin Carathéodory) states that any pre-measure defined on a given ring of subsets R of a given set Ω can be extended to a measure on the σ-algebra generated by R, and this extension is unique if the pre-measure is σ-finite. Consequently, any pre-measure on a ring containing all intervals of real numbers can be extended to the Borel algebra of the set of real numbers. This is an extremely po… WebCarathéodory's theorem.

WebCarathéodory showed that, based upon the earlier statements of the Second Law, such states exist for the flow of heat in a reversible process, so that the theorem becomes applicable to this physical process. This conclusion, which is still another way of stating the Second Law, is known as the Carathéodory principle.
