چکیده | ||
In this paper we introduce a definition of gradation of continuity in graded fuzzy topological spaces and study its various characteristic properties. The impact of the grade of continuity of mappings over the N-compactness grade is examined. Concept of gradation is also introduced in openness, closed- ness, homeomorphic properties of mappings and T2 separation axiom. Effect of the grades interrelated with N-compactness, closedness, T2 separation and homeomorphism of mappings are studied. | ||
