<em>L</em>-fuzzy upper approximation operators associated with <em>L</em>-generalized fuzzy remote neighborhood systems of <em>L</em>-fuzzy points
It is well known that the approximation operators are always primitive concepts in kinds of general rough set theories. In this paper, considering L to be a completely distributive lattice, we introduce a notion of <em>L</em>-fuzzy upper approximation operator based on <em>L</em...
