On reformulated Zagreb indices

Molecular Diversity, 2004
Zagreb indices were reformulated in terms of the edge-degrees instead of the vertex-degrees as the original Zagreb indices. Three types of Zagreb indices were considered: original, modified and variable Zagreb indices. It is found that the optimum exponent of the variable reformulated Zagreb M2 index (v = -1/2) is identical with the exponent of the ...

New formulae for Zagreb indices

AIP Conference Proceedings, 2017
In this paper, we study with some graph descriptors also called topological indices. These descriptors are useful in determination of some properties of chemical structures and preferred to some earlier descriptors as they are more practical. Especially the first and second Zagreb indices together with the first and second multiplicative Zagreb indices

ZAGREB ECCENTRICITY INDICES OF VICSEK NETWORKS

Fractals, 2022
For a connected graph, the first Zagreb eccentricity index is defined as the sum of squares of the eccentricities of the vertices, and the second Zagreb eccentricity index is defined as the sum of the products of the eccentricities of pairs of adjacent vertices.
