95. Fuzzy Subhypergroups DegreeIrina Elena Cristea, 2016, izvirni znanstveni članek Opis: In this paper we define the degree to which a fuzzy subset on a hypergroup is a fuzzy subhypergroup by means of the residuate sets, constructed using the minimum t-norm. We give also some properties of this new index connected with the intersection of a family of fuzzy subhypergroups, and respectively with the homomorphic image/preimage of a fuzzy subset. We conclude with addressing new problems related with intuitionistic fuzzy subhypergroups and fuzzy subpolygroups in the framework of our discussion. Ključne besede: Fuzzy set, fuzzy subhypergroup, residuate set, t-norm Objavljeno v RUNG: 24.06.2016; Ogledov: 4647; Prenosov: 0 Gradivo ima več datotek! Več... |

97. On complementable semihypergroupsHossien Aghabozorgi, Irina Elena Cristea, Morteza Jafarpour, 2016, izvirni znanstveni članek Opis: n this paper, we first introduce the notion of complementable semihypergroup, proving that the classes of simplifiable semigroups, groups, and complete hypergroups are examples of complementable semihypergroups. Then we define when two semihypergroups are disjoint and find examples of such semihypergroups. Finally, we discuss on the complementable property of $K_H$-hypergroups. Ključne besede: (semi)hypergroup, complementable semihypergroup, disjoint semihypergroup, $K_H$-hypergroup Objavljeno v RUNG: 03.03.2016; Ogledov: 4531; Prenosov: 1 Gradivo ima več datotek! Več... |
