From random sets to continuous tensor products: answers to three questions of W. Arveson
نویسنده
چکیده
The set of zeros of a Brownian motion gives rise to a product system in the sense of William Arveson (that is, a continuous tensor product system of Hilbert spaces). Replacing the Brownian motion with a Bessel process we get a continuum of non-isomorphic product systems.

Non-Isomorphic Product Systems
Uncountably many mutually non-isomorphic product systems (that is, continuous tensor products of Hilbert spaces) of types II0 and III are constructed by probabilistic means (random sets and off-white noises), answering four questions of W. Arveson.
متن کاملPath Spaces , Continuous Tensor Products
We classify all continuous tensor product systems of Hilbert spaces which are “infinitely divisible” in the sense that they have an associated logarithmic structure. These results are applied to the theory of E0-semigroups to deduce that every E0-semigroup possessing sufficiently many “decomposable” operators must be cocycle conjugate to a CCR flow. A path space is an abstraction of the set of ...
متن کاملDifferent-Distance Sets in a Graph
A set of vertices $S$ in a connected graph $G$ is a different-distance set if, for any vertex $w$ outside $S$, no two vertices in $S$ have the same distance to $w$.The lower and upper different-distance number of a graph are the order of a smallest, respectively largest, maximal different-distance set.We prove that a different-distance set induces either a special type of path or an independent...
متن کاملRandom Sets and Invariants for (Type II) Continuous Tensor Product Systems of Hilbert Spaces
In a series of papers [66, 65, 62, 63, 64] TSIRELSON constructed from measure types of random sets or (generalised) random processes a new range of examples for continuous tensor product systems of Hilbert spaces introduced by ARVESON [4] for classifying E0-semigroups upto cocycle conjugacy. This paper starts from establishing the converse. So we connect each continuous tensor product systems o...
متن کاملEvaluating EFL Learners’ Philosophical Mentality through their Answers to Philosophical Questions: Using Smith’s Framework
Given the role philosophical mentality can fulfill in bringing individuals the essential skills of wisdom and well thinking, the present paper, by applying Smith’s (2007) theoretical framework, strived to explore the extent philosophic-mindedness exists among the participants. Considering the fact that, a philosophic mind begets philosophical answers, the participants’ philosophical thi...
