Products 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 کاملCongruence Relations on Hypergroupoids and Nd-groupoids
In this work we prove that the set of congruences on an nd-groupoid under suitable conditions is a complete lattice which is a sublattice of the lattice of equivalence relations on the nd-groupoid. The study of these conditions allowed to construct a counterexample to the statement that the set of (fuzzy) congruences on a hypergroupoid is a complete lattice.
متن کاملRegularity of intuitionistic fuzzy relations on hypergroupoids
In this paper we introduce the notions of regular and strongly regular intuitionistic fuzzy relations on hypergroupoids, studying some related properties and connections with the classical case. Then we investigate the lattice structure of these kinds of intuitionistic fuzzy equivalences.
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...
متن کامل -hypergroups and -semihypergroups associated to binary relations
the concept of -semihypergroups is a generalization of semigroups, a generalization of semihypergroups and a generalization of -semigroups. in this paper, we study the concept of semiprime ideals in a -semihypergroup and prove some results. also, we introduce the notion of -hypergroups and closed -subhypergroups. finally, we study the concept of -semihypergroups associated to binary...
