Abstract
As a topological index closely related to the physical, chemical and biological properties of compounds, graph indexes have been concerned and studied by scholars. This paper defined the concept of " Level-Contribution " from the view of degree and distance. On the basis of this, we studied the Vertex-Gutman-Index and Graph-Gutman-Index of the concurrent and double circle graph, and obtained the extremal values of the Vertex-Gutman of the vertices and extremal graphs of the Graph-Gutman-Index of the concurrent and double circle graph.
