e-open Maps and Homeomorphisms in Fermatean Neutrosophic Topological Spaces with Applications to Entropy Measures

In this article, we introduce the concepts of FNe-open and FNe-closed mappings in Fermatean neutrosophic topological spaces and study some of their related properties. Further, the work is extended to FNe-homeomorphism, FNe-C homeomorphism, and FNeT1 2-space in Fermatean neutrosophic topological spaces, and some of their related attributes are established. Also we give an real life application for decision making using entropy measure on Fermatean Neutrosophic sets.
