Abstract
Neutrosophic theory has many applications in graph theory, single valued neutrosophic graph (SVNG) is the generalization of fuzzy graph and intuitionistic fuzzy graph. In this paper, we introduced some types of SVNGs, which are subdivision SVNGs, middle SVNGs, total SVNGs and single valued neutrosophic line graphs (SVNLGs), also discussed the isomorphism, co weak isomorphism and weak isomorphism properties of subdivision SVNGs, middle SVNGs, total SVNGs and SVNLGs.
