Al Al-Hamido Department of Mathematics, College of Science, AlBaath University, Homs, Syria Luai Salha Department of Mathematics, College of Science, AlBaath University, Homs, Syria Taleb Gharibah The main goal of this paper is to propose a new type of separation axioms via neutrosophic crisp semi open sets and neutrosophic crisp points in neutrosophic crisp topological spaces, namely neutrosophic crisp semi separation axioms. 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 2020 32 40 10.54216/IJNS.060105 https://www.americaspg.com/articleinfo/21/show/429
