WebRecently, more work has been done on obstructions to the coarse embedding of graphs and general metric spaces into Hilbert space. Ostrovskii [4] and Tessera [8] characterize non-embeddability into Hilbert space in terms of a family of subgraphs exhibiting expander-like properties, and Ostrovskii [5] further shows that graphs with no K. r WebJul 20, 2016 · TL;DR: Is there a version of the Bochner integral which allows for the integration of isometric embeddings $\phi:X\to H$ from a metric space to a Hilbert space, satisfying $\int_X \ \phi\ d\mu < \infty$ for finite Borel measures $\mu$?

Assume that X = ⋃ n F n with H -closed sets F n.
WebJun 26, 2024 · A semi-metric space admits an isometric embedding into a Hilbert space iff it is of 2-negative type. Besides 2-negative type characterizing isometric embeddability into a Hilbert space, the following theorem states the important property that negative type is downward closed. Theorem 11 (Wells and Williams 1975, Theorem 4.7). WebBanach space with a S-basis can be densely and continuously embedded into a Hilbert space which is unique up to a change of basis. 1. Introduction In 1965, Gross [G] proved that every real separable Banach space contains a separable Hilbert space as a dense embedding, and this space is the support of a Gaussian measure.
