Abstract
Based on the concept of limit of prefilters and residual
implication, several notions in fuzzy topology are fuzzyfied in
the sense that, for each notion, the degree to which it is
fulfilled is considered. We establish therefore theories of
degrees of compactness and relative compactness, of closedness,
and of continuity. The resulting theory generalizes the
corresponding “crisp” theory in the realm of fuzzy convergence
spaces and fuzzy topology.
