Blaschke selection theorem : ウィキペディア英語版 | Blaschke selection theorem The Blaschke selection theorem is a result in topology and convex geometry about sequences of convex sets. Specifically, given a sequence of convex sets contained in a bounded set, the theorem guarantees the existence of a subsequence and a convex set such that converges to in the Hausdorff metric. The theorem is named for Wilhelm Blaschke. ==Alternate statements==
* A succinct statement of the theorem is that a metric space of convex bodies is locally compact. * Using the Hausdorff metric on sets, every infinite collection of compact subsets of the unit ball has a limit point (and that limit point is itself a compact set).
