Random compact set : ウィキペディア英語版 | Random compact set In mathematics, a random compact set is essentially a compact set-valued random variable. Random compact sets are useful in the study of attractors for random dynamical systems. ==Definition==
Let be a complete separable metric space. Let denote the set of all compact subsets of . The Hausdorff metric on is defined by : is also а complete separable metric space. The corresponding open subsets generate a σ-algebra on , the Borel sigma algebra of . A random compact set is а measurable function from а probability space into . Put another way, a random compact set is a measurable function such that is almost surely compact and : is a measurable function for every .
