W.F.Al Omeri In this article, Bipolar neutrosophic nano topology is introduced and some of its properties are studied. We found that, it is difficult to find a nano topology for every bipolar neutrosophic set. So we introduced a bipolar neutrosophic nano  topology, which is a generalization of bipolar neutrosophic nano topology and its fundamental features are investigated with appropriate examples. This approach is used for real life multi criteria decision making situations. The practical problems may be solved by finding CORE values through the criterion reduction.One can apply the basis of the bipolar neutrosophic nano  topology as the key factors of  a particular decision making problem using topological reduction of attributes in complete or incomplete information system. 2022 2022 19 31 10.54216/JNFS.030202 https://www.americaspg.com/articleinfo/24/show/1154
