Filters in fuzzy class theory
Graded properties are a natural tool in connection with graded membership or truth degrees. The author considers here the basic notions and ideas of filter theory and generalizes them, in a natural way, using the formal background of fuzzy class theory as conceived by \textit{L. Běhounek} and \textit{P. Cintula} [Fuzzy Sets Syst. 154, No.~1, 34--55 (2005; Zbl 1086.03043)] and developed within the framework of the mathematical fuzzy logic \(\mathrm{\L}\Pi_{\triangle}\).
