Next, we clarify the links between them and investigate their properties. Finally, we consider them under intersection, cartesian product and homomorphisms(image and pre image) and we study related properties.}, keywords = {Algebra and orders,theory of fuzzy sets,Norms,products and intersections,homomorphisms}, url = {https://www.macajournal.com/article_686982.html}, eprint = {https://www.macajournal.com/article_686982_fc6c8fb4892255ba0c2a9fba6a36f5dc.pdf} }
