Different operators were defined over intuitionistic fuzzy sets throughout the years.
In May 1983 the modal operators necessity and possibility were defined. In October 1983 the topological operators closure and interior followed. Later, the relations between the modal and the topological operators were studied and published[1].
Modal type operators
Necessity and possibility

Operator Gα,β
Operators Hα,β , H*α,β , Jα,β and J*α,β
Operator Xa,b,c,d,e,f
Topological operators
Closure and interior
Level operators
Operators ! and ?
