WebCarathéodory Theorem. One of the basic results ( [ 3 ]) in convexity, with many applications in different fields. In principle it states that every point in the convex hull of a set S ⊂ R n can be represented as a convex combination of a finite number ( n + 1) of points in the set S. See for example [ 7 ], [ 9 ], [ 4 ], [ 1 ], [ 6 ], [ 10 ]. 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.
