On four intuitionistic fuzzy feeble topological structures
Krassimir Todorov Atanassov · 2022
The concepts of an Intuitionistic Fuzzy Feeble Topological Structure (IFFTS) and Intuitionistic Fuzzy Modal Feeble Topological Structure (IFMFTS) are introduced. It is proved that the two extended intuitionistic fuzzy topological operators ${\mathcal{C}^{\varepsilon ,\eta }}$ and ℐε,ηgenerate IFFTSs, and together the two standard intuitionistic fuzzy modal operators □ and ♢ they generate IFMFTSs. Some basic properties of these structures are discussed.
