Borel reducibility and finitely Hölder(α) embeddability
Let (Xn, dn), n ∈ N be a sequence of pseudo-metric spaces, p ≥ 1. For x, y ∈ ∏n∈NXn, let (x, y) ∈ E((Xn)n∈N; p) ⇔ ∑ n∈N dn(x(n), y(n)) p < +∞. For Borel reducibility between equivalence relations E((Xn)n∈N; p), we show it is closely related to finitely Hölder(α) embeddability between pseudometric spaces.
متن کاملOn Hölder Projective Divergences
We describe a framework to build distances by measuring the tightness of inequalities, and introduce the notion of proper statistical divergences and improper pseudo-divergences. We then consider the Hölder ordinary and reverse inequalities, and present two novel classes of Hölder divergences and pseudo-divergences that both encapsulate the special case of the Cauchy-Schwarz divergence. We repo...
متن کاملDirectional Hölder Metric Regularity
This paper sheds new light on regularity of multifunctions through various characterizations of directional Hölder/Lipschitz metric regularity, which are based on the concepts of slope and coderivative. By using these characterizations, we show that directional Hölder/Lipschitz metric regularity is stable, when the multifunction under consideration is perturbed suitably. Applications of directi...
متن کاملThe Jordan-Hölder Theorem
This submission contains theories that lead to a formalization of the proof of the Jordan-Hölder theorem about composition series of finite groups. The theories formalize the notions of isomorphism classes of groups, simple groups, normal series, composition series, maximal normal subgroups. Furthermore, they provide proofs of the second isomorphism theorem for groups, the characterization theo...
متن کاملHölder Stable Minimizers, Tilt Stability, and Hölder metric Regularity of Subdifferentials
Using techniques of variational analysis and dual techniques for smooth conjugate functions, for a local minimizer of a proper lower semicontinuous function f on a Banach space, p ∈ (0, +∞) and q = 1+p p , we prove that the following two properties are always equivalent: (i) x̄ is a stable q-order minimizer of f and (ii) x̄ is a tilt-stable p-order minimizer of f . We also consider their relation...
