In this paper, we dene the concept of level graphs on interval-valued fuzzy graphs (IVFGs) and introduce the notions of [, ]− [, ]− homomorphism, isomorphism, weak isomorphism, and co-weak isomorphism of IVFGs by [, ]− homomorphism. Also, an application of homomorphism of IVFGs has been presented by using coloring-FG.
