A Variation Embedding Theorem and Applications
Fractional Sobolev spaces, also known as Besov or Slobodetzki spaces, arise in many areas of analysis, stochastic analysis in particular. We prove an embedding into certain q-variation spaces and discuss a few applications. First we show q-variation regularity of Cameron-Martin paths associated to fractional Brownian motion and other Volterra processes. This is useful, for instance, to establis...
متن کاملA subgaussian embedding theorem
We prove a subgaussian extension of a Gaussian result on embedding subsets of a Euclidean space into normed spaces. Using the concentration of a random subgaussian vector around its mean we obtain an isomorphic (rather than almost isometric) result, under an additional cotype assumption on the normed space considered.
متن کاملThe index theorem of regular variation and its applications
We develop further the topological theory of regular variation of [BOst13]. There we established the uniform convergence theorem (UCT) in the setting of topological dynamics (i.e. with a group T acting on a homogenous space X), thereby unifying and extending the multivariate regular variation literature. Here, working with realtime topological ows on homogeneous spaces, we identify an index of...
متن کاملNon - Quasiconvexity Embedding Theorem
We show that if G is a non-elementary torsion-free word hyperbolic group then there exists another word hyperbolic group G, such that G is a subgroup of G but G is not quasiconvex in G.
متن کاملNagata’s Embedding Theorem
In 1962–63, M. Nagata showed that an abstract variety could be embedded into a complete variety. Later, P. Deligne translated Nagata’s proof into the language of schemes, but did not publish his notes. This paper, which is to appear as an appendix in a forthcoming book, gives an elaboration of Deligne’s notes. It also contains some complementary results on extending divisors and vector sheaves ...
