  • Edge-contributions of some topological indices and arboreality of molecular graphs
    Pisanski, Tomaž ; Žerovnik, Janez, 1958-
    Some graph invariants can be computed by summing certain values, called edge-contributions over all edges of graphs. In this note we use edge-contributions to study relationships among three graph ... invariants, also known as topological indices in mathematical chemistry: Wiener index, Szeged index and recently introduced revised Szeged index. We also use the quotient between the Wiener index and the revised Szeged index to study tree-likeness of graphs.
