In this paper a property which can be used to Baire spaces in fy. neutrosophic top. Spaces (simply as fy. – fuzzy, top. – topological) are introduced and studied. For this purpose, introduced fy. neutrosophic Fσ set, fy. neutrosophic Fδ set, fy. neutrosophic dense, fy. neutrosophic nowh. (Simply as nowh. - nowhere) dense, fy. neutrosophic one (one denotes first) category, fy. neutrosophic two (two denotes second) category and fy. neutrosophic re. (Simply as re. – residual) set are defined. Also, some characterizations about these concepts are obtained. © 2022,Neutrosophic Sets and Systems. All Rights Reserved.
