Abstract: In this paper, the new notions of the degrees of compactness, countable compactness and Lindelöf property are introduced in (L, M)-fuzzy supratopological spaces. The notions of pre-compactness, semi-compactness and sp-compactness in (L, M)-fuzzy topological spaces can be viewed as special cases of compactness in (L, M)-fuzzy supratopological spaces.
Keywords: (L, M)-fuzzy supratopology, compactness, countable compactness, the Lindelöf property
