Finally, we examine the relationship between them in details. And also includes the study of the connections between these neutrosophic crisp semi separation axioms and the existing neutrosophic crisp separation axioms. Moreover, many examples are presented, to illustrate the concepts introduced in this paper. and investigate their fundamental properties, relationships and characterizations. 2020 32 40 429 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.060105 https://www.americaspg.com/journal/21/article/429 https://www.americaspg.com/storage/5947.pdf
