Salih Department of Mathematics, College of Science, University of Duhok, Kurdistan Region, Iraq Alias B. Khalaf In this paper we apply the neutrosophic set on the concept of the UP-algebra to obtain some types of neurosophic sets satisfies certain conditions which are called neutrosophic Up-subalgebras. Several types of these neutrosophic Up-subalgebras are introduced and their properties are investigated. Also, illustrative examples are given when they are needed. 2025 2025 67 77 10.54216/IJNS.260207 https://www.americaspg.com/articleinfo/21/show/3699
