A Cone-Theoretic Krein-Milman Theorem

WebThe classical Krein-Milman Theorem states that any compact convex subset K of a locally convex topological vector space X is the closed convex hull of its extreme points. We show that a similar result holds when X is a locally convex topological cone. Remarkably, the only visible modification in the conclusion of the theorem is that WebIn functional analysis, the Krein–Rutman theorem is a generalisation of the Perron–Frobenius theorem to infinite-dimensional Banach spaces. It was proved by Krein and Rutman in 1948. Statement. Let be a Banach space, and let be a convex cone such ...

WebNext, the work investigates applications of the Krein-Milman theorem to representation theory and elements of Choquet theory. A sandwich theorem of intercalating an affine function h h between f f and g , g, where f f\hspace{.25em} and – g \mbox{--}g are convex, f ≤ g f\le g on a finite-simplicial set, is recalled. Web'Krein–Milman Theorem' published in 'Encyclopedia of Optimization' Let us assume that the theorem is true for all convex compact sets of dimension d − 1 ≥ 0. If x ∈ C, but not in conv(S), there exists a line segment in C such that x is in the interior of it (since x is not an extreme point). This line segment intersects the (relative) boundary of C in two points u …
