Shabir Department of Mathematics Quaid-i-Azam University, Islamabad, Pakistan N. Rehman Department of Mathematics Quaid-i-Azam University, Islamabad, Pakistan Journal Article 2011 11 27 In this paper we have generalized the concepts of ,q-fuzzy ideals, ,q-fuzzy quasi-ideals and<br />,q-fuzzy bi-ideals by introducing the concepts of   k ,q -fuzzy ideals,   k ,q -fuzzy quasiideals and   k ,q -fuzzy bi-ideals in ternary semigroups and several related properties are investigated. Different characterizations of regular and weakly regular ternary semigroups by the properties of these ideals are given. Ternary semigroups   k ,q -fuzzy ideals   k ,q -fuzzy quasi-ideals   k ,q - fuzzy bi-ideals https://ijsts.shirazu.ac.ir/article_2093_57f7ed00a6d5cfe0e7519f9746427aae.pdf
