Intuitionistic Fuzzy Sublattices and Ideals

Abstract: We study the concept of intuitionistic fuzzy sublattices and intuitionistic fuzzy ideals of a lattice. Some characterization and properties of these intuitionistic fuzzy sublattices and ideals are established. Also we introduce the sum and product of two intuitionistic fuzzy ideals and prove that the sum and product of two Intuitionistic fuzzy ideals of a distributive lattice is again an intuitionistic fuzzy ideal. Moreover, we study the properties of intuitionistic fuzzy ideals under lattice homomorphism.

“…The concept of intuitionistic fuzzy lattice was introduced by Thomas and Nair [30] as an intuitionistic fuzzy set on a crisp lattice stable by the supremum and the infimum of the binary operations ⊓ and ⊔. For further details on intuitionistic fuzzy lattices, we refer to [24,29,30].…”

“…Qin and Liu [21,26] introduced and investigated the properties of intuitionistic fuzzy filters on a residuated lattice. Thomas and Nair [29,30] studied intuitionistic fuzzy sublattices, intuitionistic fuzzy ideals and intuitionistic fuzzy filters on a lattice. In [35], Xu introduced the notion of interval valued intuitionistic (T, S)-fuzzy filter on a lattice implication algebra and some basic properties of it were obtained.…”

“…Later, Ajmal and Thomas [5] specifically applied the concept of FSs in lattice theory and developed the theory of fuzzy sublattices (FSLs). Thereafter, Thomas and Nair [3] introduced the concept of intuitionistic fuzzy sublattices (IFSLs) in 2011. Characterization of intuitionistic fuzzy ideals and filters based on lattice operations were studied by Milles [11] in 2017.…”
