Abstract
A topological index is the graph invariant numerical descriptor calculated from a molecular graph representing a molecule. Classical Zagreb indices and the recently introduced Zagreb coindices are topological indices related to the atom ? atom connectivity of the molecular structure represented by the graph G. We explore here their basic mathematical properties and present explicit formulae for these new graph invariants under several graph operations.
