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. It states that if a point $${\displaystyle x}$$ lies in the convex hull $${\displaystyle \mathrm {Conv} (P)}$$ of a set $${\displaystyle P\subset \mathbb {R} ^{d}}$$, … See more • Shapley–Folkman lemma • Helly's theorem • Kirchberger's theorem • Radon's theorem, and its generalization Tverberg's theorem • Krein–Milman theorem See more Carathéodory's number For any nonempty $${\displaystyle P\subset \mathbb {R} ^{d}}$$, define its Carathéodory's number to be the smallest integer $${\displaystyle r}$$, such that for any $${\displaystyle x\in \mathrm {Conv} (P)}$$, … See more • Eckhoff, J.

Let X ⊂ R d. Then each point of c o n v ( X) can be written as a convex combination of at most d + 1 points in X. From the proof, each y ∈ c o n v ( X) can be written as the following convex combination, where we assume k ≥ d + 2: y = ∑ j = 1 k λ j x j with ∑ j = 1 k λ j = 1 and λ j > 0 ∀ j = 1, …, k coat supplements for dogs
