Abstract:A λ harmonic graph G, a λ-Hgraph G for short, means that there exists a constant denotes the degree of vertex vi. In this paper, some harmonic properties of the complement and line graph are given, and some algebraic properties for the λ-Hgraphs are obtained.
Keywords:harmonic graph  regular graph  line graph  degree series
