Measures of compactness in L-fuzzy pretopological spaces

Abstract: In this paper, we introduce the concepts of the degrees of compactness, countable compactness and Lindelöf property in L-fuzzy pretopological spaces by means of implication operator. These definitions do not rely on the structure of the basis lattice L and no distributivity in L is required. The notions of pre-compactness and semi-compactness in L-fuzzy topological spaces can be viewed as special cases of compactness in L-fuzzy pretopological spaces. Their properties are investigated. Further when L is complet… Show more

“…The analysis of compactness of the fuzzy sets and topological spaces is important for formulating corresponding measures [9]. The degree of compactness and countability in L-fuzzy pretopological spaces can be analyzed [10]. The formulation of pretopological spaces is based on the combination of a non-distributive lattice and implication operator algebra.…”
