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.

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 ...

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.
