Characterizing completable fuzzy metric spaces. (English) Zbl 1057.54010

The work deals with the separation of points in intuitionistic fuzzy topological spaces (IFTS). The Hausdorfness of an IFTS is described in terms of convergence of nets. It is shown that an IFTS is \(T_2\) if and only if each convergent intuitionistic fuzzy net has a unique limit. Weakened properties of fuzzy Hausdorfness and \(q\)-Hausdorffness are introduced and characterised.
