WebA simple geometrical argument is used to establish seemingly different continuous and discrete hang-hang type results. Among other applications we discuss the bang-bang principle for linear continuous control systems, a generalization to discrete systems, the ranges of vector integrals, the Shapley–Folkman lemma and the Carathéodory theorem, … WebNov 30, 2024 · Let us build a distribution Q ′ ′, related to Q ′ and concentrated on the finite number of points from ext (X), where ext (·) denotes a set of extreme points. By the Krein-Milman theorem (see, for example, Theorem 4.2 of Reference .) and the Caratheodory theorem (see, for example, Theorem 2.4 of Reference ) for each point x i, t = 1 ... is an enzyme that unwinds the dna strand

The first result is the representation theorem (e.g., [], []), which states that: the set of extreme points p i, i ∈ , of the polyhedral set X is nonempty and finite;. the set of extreme directions d i, i ∈ , is empty if and only if X is bounded, and if X … is an enzyme an organelle

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.
