Rough sets in Fuzzy Neutrosophic approximation space

A rough set is a formal approximation of a crisp set which gives lower and upper approximation of original set to deal with uncertainties. The concept of neutrosophic set is a mathematical tool for handling imprecise, indeterministic and inconsistent data. In this paper, we introduce the concepts of Rough Fuzzy Neutrosophic Sets and Fuzzy Neutrosophic Rough Sets and investigate some of their properties. Further as the characterisation of fuzzy neutrosophic rough approximation operators, we introduce various notion of cut sets of neutrosophic fuzzy sets.
