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.

Definability properties and the congruence closure

Archive for Mathematical Logic, 1990
The author defines a notion of a thin quantifier and uses it to prove some interesting general results of the failure of the \(\Delta\)- interpolation theorem and Beth's definability theorem in logics defined from generalized quantifiers. Many of the results of the paper are connected to the failure of the uniform reduction property for quotients.

Closure properties for the class of behavioral models

Theoretical Computer Science, 2007
Hidden k-logics can be considered as the underlying logics of program specification. They constitute natural generalizations of k-deductive systems and encompass deductive systems as well as hidden equational logics and inequational logics.

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.

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 ...

Insertion operations: Closure properties

Bull. EATCS, 1993
The paper investigates closure properties of families of languages (in Chomsky hierarchy) under various variants of insertion operations as introduced by the author [On insertion and deletion operations in formal languages, PhD Thesis, Univ. of Turku, Dept. of Math., 1991].
