Contra Continuous and Irresolute Maps via M-open Sets in n-Cylindrical Neutrosophic Topological Spaces

In this paper, n-cylindrical neutrosophic contra M -continuous mappings are defined and investigated within the framework of n-cylindrical neutrosophic topological spaces. Motivated by recent developments on neutrosophic contra continuous functions, irresolute mappings, and n-cylindrical fuzzy neutrosophic topological structures, several fundamental properties of n-cylindrical neutrosophic contra M -irresolute mappings are established. The results obtained extend and complement existing studies on various classes of Neutrosophic contra continuous and contra irresolute mappings, thereby enriching the theory of neutrosophic topological spaces and providing a basis for further applications of n-cylindrical neutrosophic mappings.
