Poongothai Associate Professor, PG & Research Department of Mathematics, Shanmuga Industries Arts and Science College, Tiruvannamalai-606603, Tamilnadu, India E. Kalaivani Ph.D(Full-time) Research Scholar, PG & Research Department of Mathematics, Shanmuga Industries Arts and Science College, Tiruvannamalai-606 603, Tamilnadu, India The aim of this paper is to introduce the concept of fuzzy neutrosophic boundary and fuzzy neutrosophic semi-boundary of a fuzzy neutrosophic topological space. Some characterization are discussed. Several examples and properties are obtained.
