Ali Abbas Ministry of Education, Directorate General of Education/ Baghdad/ Al-Kark/3, Baghdad, Iraq Shuker Mahmood Khalil Department of Mathematics, College of Science, Basrah University, Basrah, Iraq Journal Article 2020 09 20 The aim of this paper is to investigate some new types of neutrosophic continuous mappings like, neutrosophic α ∗−continuous mapping (Nα∗ − CM), neutrosophic irresolute α∗−continuous mapping (NIα∗ − CM), and neutrosophic strongly α∗−continuous mapping (NSα∗ − CM) are given and some of their properties are studied. Moreover, new kind of neutrosophic contra continuous mappings is investigated in this work, it is called neutrosophic contra α∗−continuous mapping (NCα∗ − CM). neutrosophic sets neutrosophic topological space neutrosophic $alpha$ -open sets neutrosophic $alpha^{*}$ -open set https://ijnaa.semnan.ac.ir/article_4910_f0deb9709de757ec48d25404598ce8ec.pdf
