On non-separable components of hyperspaces with the Hausdorff metric [PDF]

open access: yesМатематичні Студії, 2011
Let $(X,d)$ be a connected non compact metric space. Suppose the metric$d$ convex and such that every closed bounded subset of $X$ is compact. Let $F(X)$ bethe space of nonvoid closed subsets of $X$ with the Hausdorff distance associated to $d$.We prove ...

Connectedness of Solution Sets for Weak Vector Variational Inequalities on Unbounded Closed Convex Sets

open access: yesAbstract and Applied Analysis, 2013
We study the connectedness of solution set for set-valued weak vector variational inequality in unbounded closed convex subsets of finite dimensional spaces, when the mapping involved is scalar C-pseudomonotone.

On unbounded Bergman operators [PDF]

open access: yes, 2003
This paper explores properties of the Bergman operator on unbounded open subsets of the plane. In addition to the characterization of the bounded commutant of such operators it proves the Berger–Shaw theorem and gives some general criteria under which ...

Differentially private posterior summaries for linear regression coefficients

open access: yesThe Journal of Privacy and Confidentiality, 2018
In Bayesian regression modeling, often analysts summarize inferences using posterior probabilities and quantiles, such as the posterior probability that a coefficient exceeds zero or the posterior median of that coefficient.

Joint measurability structures realizable with qubit measurements: Incompatibility via marginal surgery

open access: yesPhysical Review Research, 2020
Measurements in quantum theory exhibit incompatibility, i.e., they can fail to be jointly measurable. An intuitive way to represent the (in)compatibility relations among a set of measurements is via a hypergraph representing their joint measurability ...

Forcing closed unbounded subsets of \(\aleph_{\omega_{1}+1}\)

open access: yesThe Journal of Symbolic Logic, 2013
Summary: Using square sequences, a stationary subset \(S_T\) of \(\aleph_{\omega_{1}+1}\) is constructed from a tree \(T\) of height \(\omega_1\), uniformly in \(T\). Under suitable hypotheses, adding a closed unbounded subset to \(S_T\) requires adding a cofinal branch to \(T\) or collapsing at least one of \(\omega_1\), \(\aleph_{\omega_{1}}\), and \(

Delocalization of light in photonic lattices with unbounded potentials

open access: yes, 2023
In classical mechanics, a particle cannot escape from an unbounded potential well. Naively, one would expect a similar result to hold in wave mechanics, since high barriers make tunneling difficult.

Distribution of T-lymphocyte subsets in porcine lymphoid tissues [PDF]

open access: yes, 1987
The distribution of the functional subsets of porcine T cells, the cytolytic/suppressor (Tc/s) and the helper/inducer (Th/i) cells was studied in cryostat sections of thymus, lymph nodes, tonsils, Peyer's patches, spleen and liver using the indirect ...

Functor of extension of $\Lambda$-isometric maps between central subsets of the unbounded Urysohn universal space

open access: yes, 2010
summary:The aim of the paper is to prove that in the unbounded Urysohn universal space $\mathbb U$ there is a functor of extension of $\Lambda $-isometric maps (i.e. dilations) between central subsets of $\mathbb U$ to $\Lambda $-isometric maps acting on

Unbounded B-Fredholm operators on Hilbert spaces [PDF]

open access: yes, 2008
This paper is concerned with the study of a class of closed linear operators densely defined on a Hilbert space H and called B-Fredholm operators.
