Binary relations and reduced hypergroups

چکیده
Different partial hypergroupoids are associated with binary relations defined on a set H. In this paper we find sufficient and necessary conditions for these hypergroupoids in order to be reduced hypergroups. Given two binary relations and on H we investigate when the hypergroups associated with the relations ∩ , ∪ and are reduced. We also determine when the cartesian product of two hypergroupoids associated with a binary relation is a reduced hypergroup. © 2007 Elsevier B.V. All rights reserved. MSC: 20N20; 04A05

Enumeration of Rosenberg hypergroups
The aimof this paper is to introduce the notion of generalmutually associative hypergroups and to give some properties of the hypergroups associated with binary relations related to these notions. A program written in C# computes the number of Rosenberg hypergroups that satisfies the property of (general) mutual associativity. © 2010 Elsevier Ltd. All rights reserved.
متن کاملN-hypergroups and Binary Relations
In this paper, we introduce and study the notion of a partial n-hypergroupoid, associated with a binary relation. Some important results concerning Rosenberg partial hypergroupoids, induced by relations, are generalized to the case of n-hypergroupoids. Then, n-hypergroups associated with union, intersection, products of relations and also mutually associative n-hypergroupoids are analyzed. Fina...
متن کاملEnumeration of Rosenberg-type hypercompositional structures defined by binary relations
Every binary relation ρ on a set H, (card(H) > 1) can define a hypercomposition and thus endow H with a hypercompositional structure. In this paper the binary relations are represented by Boolean matrices. With their help, the hypercompositional structures (hypergroupoids, hypergroups, join hypergroups) that derive with the use of the Rosenberg’s hyperoperation, are characterized, constructed a...
متن کاملProducts of hypergroupoids associated to binary relations
We study closure properties with respect to products for hypergroupoids, semihypergroups and hypergroups associated to binary relations. Using some basic category theory tools, from a certain point, the investigation turns into studying closure properties with respect to direct products for some classes of monounary multialgebras.
متن کاملNeutrosophic Hypercompositional Structures defined by Binary Relations
The objective of this paper is to study neutrosophic hypercompositional structures ( ) H I arising from the hypercompositions derived from the binary relations τ on a neutrosophic set ( ) H I . We give the characterizations of τ that make ( ) H I hypergroupoids,quasihypergroups, semihypergroups, neutrosophic hypergroupoids, neutrosophic quasihypergroups, neutrosophic semihypergroups and neu...
