UNCOUNTABLE ORTHOGONALITY IS A CLOSURE PROPERTY

Bulletin of the London Mathematical Society, 2001
It is shown that, for λ > ω, λ-orthogonality classes in locally λ-presentable categories coincide with full subcategories that are closed under limits and under λ-directed colimits. This comes as a surprise, since the statement is known to be false for λ = ω.

Some Properties of θ-Closure

Canadian Journal of Mathematics, 1981
The concept of θ-closure was introduced by Velicko to study H-closed spaces and to generalize Taimanov's extension theorem [11], [12]. More recently, this notion has been used by Dickman and Porter [1] to characterize those Hausdorff spaces in which the Fomin H-closed extension operator commutes with the projective cover (absolute) operator and [2] to ...

Closure properties of the relevation transform*

Naval Research Logistics Quarterly, 1985
AbstractSufficient conditions under which the relevation of two probability distributions is (i) NBU, (ii) IFRA, (iii) IFR are derived. The result for case (iii) corrects an error in a previous article by Baxter.

Electrophysiological Properties of Laryngeal Reflex Closure

Acta Oto-Laryngologica, 1971
Reflex responses were elicited in the recurrent laryngeal nerve by electrical stimulation of any sensory nerve trunk in the laryngo-pharyngeal region. Electrical stimulation of the internal branch of the superior laryngeal nerve produced: (1) Reflex response in each laryngeal muscle including the posterior cricoarytenoid.

Some Closure Properties of Finite Definitions

Studia Logica, 2001
Systems where circular definitions are allowed and the defined predicates are associated with revision rules (instead of extensions) have been studied by Gupta and Belnap. The set of finite definitions is not recursive (Gupta), so there arises the problem to characterize this set in terms of closure conditions.

On some closure-preserved properties

Archiv der Mathematik, 1987
The purpose of this paper is to show that, in a group G with unique roots, certain group-theoretic properties of a subgroup H are preserved when one considers the closure of H in G. Several such properties going from nilpotency to local nilpotency are studied from this point of view. Some consequences for group localization are also indicated.

Closure property for free electrons

International Journal of Quantum Chemistry, 1993
AbstractSome operators considered conventionally as Hermitian are not strictly Hermitian for the freeelectron states known especially in the case of solids. The consequences of this fact on the closure property are examined. © 1993 John Wiley & Sons, Inc.

Conditional and Closure Properties

2001
The union theorem, introduced in section 8.2.3, is the main tool for the study of asynchronous compositions of programs. The major virtue of this theorem is that it provides a simple rule for deducing the co-properties and transient predicates of a system from those of its component boxes. The major shortcoming is that it does not provide a simple rule
