Abstract
We define the generalized fuzzy neighbourhood systems onthe set of fuzzy points in a nonempty setXand investigate their properties by using a new interior operator. With the help of these conceptswe introduce generalized fuzzy continuity, which include many of thevariations of fuzzy continuity already in the literature, as special cases
