Résumé

The notion of stress of a vertex in a graph was introduced by Alfonso Shimbel in 1953. The stress of a vertex in a graph is the number of shortest paths passing through that vertex. In this paper, we introduce the concept of vertex stress polynomial of a graph and obtain some results including a characterization of graphs with vertex stress polynomial a non-zero constant.
