Abstract

In order to balance uncertainty, a reasonable approximation of a crisp set that yields lower as well as upper approximations of the set are done. Here, first, a special class of Fermatean Neutrosophic Set by associating the Neutrosophic Set and Fermatean Fuzzy Set is devised. A relatively new concept of Fermatean Neutrosophic Approximation Space and Fermatean Neutrosophic approximation operators are introduced. In this context, a new class of Fermatean Neutrosophic Rough set is established and a few of its characteristics are mentioned. Also, the cut sets of Fermatean Neutrosophic Rough sets, which characterize Fermatean Neutrosophic rough approximation operators are investigated.
