Partition Relations and Transitivity Domains of Binary Relations

Journal of the London Mathematical Society, 1967
The main theorem is Theorem 2: For all positive integers \(m\) and \(n\), for some positive integer \(l(m,n)\), for each ordinal number \(\alpha\), \(\omega_\alpha l(m,n) \to (m,\omega_\alpha n)^2\); if \(l_\alpha(m,n)\) is the least such \(l(m,n)\) for a given \(\alpha\), then \(\gamma \mapsto(m,\omega_\alpha n)^2\) for each \(\gamma > \omega_\alpha ...

Relational Transitions and Stress

2020
Abstract This chapter examines transitions that occur over the lifespan of romantic relationships, with a focus on marriages or partnerships with a similar long-term commitment. The chapter evaluates transitions that mark the early years of marriage (getting married and becoming parents), are sparked by unexpected challenges during the ...

Peer relations in the transition to adolescence

2002
Publisher Summary This chapter deals with two social and emotional competencies—friendship quality and self-regulation. Children's perceptions of the quality of their close friendships are direct measure of an affective peer relationship. Self-regulation as perceived by others may be considered an indirect measure of peer relations.

On the transitivity of the relation β in semihypergroups

Rendiconti del Circolo Matematico di Palermo, 1996
A significant result in the hypergroup theory is the one given by D. Freni in 1991, that is that in a hypergroup \(\beta=\beta^*\). The aim of the paper under review is to characterize semihypergroups in which the relation \(\beta\) is transitive. The main theorem gives a necessary and sufficient condition such that \(\beta\) is transitive.

On computing the transitive closure of a state transition relation

Proceedings of the 30th international on Design automation conference - DAC '93, 1993
We describe a new, recursive-descent procedure for the computation of the transitive closure of a transition relation. This procedure is the classic binary matrix procedure of [1], adapted to a BDD data structure. We demonstrate its efficacy when compared to standard iterative methods.

TRANSITIVITY OF  -RELATION ON HYPERMODULES

2008
iV In this paper we consider a strongly regular relation ƒa on hypermodules so that the quotient is amodule (with abelian group) over a fundamental commutative ring. Also, we state necessary and sufficientconditions so that the relation ƒa is transitive, and finally we prove that ƒa is transitive on hypermodules.

RELATIONS ADMITTING A TRANSITIVE GROUP OF AUTOMORPHISMS

Mathematics of the USSR-Sbornik, 1975
The concepts of a Cayley relation of arbitrary arity and a quotient relation are defined. Cayley relations are characterized as those relations whose automorphism groups contain regular subgroups. The freedom of Cayley relations is proved: any relation with a transitive automorphism group is isomorphic to a quotient relation of a Cayley relation.Using ...
