Edge-contributions of some topological indices and arboreality of molecular graphsPisanski, 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.Source: Ars mathematica contemporanea. - ISSN 1855-3966 (Vol. 2, no. 1, 2009, str. 49-58)Type of material - article, component part ; adult, seriousPublish date - 2009Language - englishCOBISS.SI-ID - 15158617
