Abstract: A definition of the concept intuitionistic fuzzy set (IFS) is given, the latter being a generalization of the concept 'fuzzy set' and an example is described. Various properties are proved, which are connected to the operations and relations over sets, and with modal and topological operators, defined over the set of IFS's.
Keywords: Intuitionistic fuzzy set, Fuzzy set, Modal operator (necessity, possibility), Topological operator (interior, closure).
