On Zagreb Eccentricity Indices [PDF]
, 2011 Zagreb eccentricity indices were proposed analogously to Zagreb indices already known and used for almost forty years. For a connected graph, the first Zagreb eccentricity index is defined as the sum of the squares of the eccentricities of the vertices,

The vertex Zagreb indices of some graph operations [PDF]
, 2016 Recently, Tavakoli et al. introduced a new version of Zagreb indices, named as vertex Zagreb indices. In this paper explicit expressions of different graphs operations of vertex Zagreb indices are presented and also as an application, explicit formulas ...

Fuzzy Zagreb Indices and Some Bounds for Fuzzy Zagreb Energy [PDF]
, 2021 Topological indices M1/M2 known as first/second Zagreb indices are defined as the sum of the sum/product of degrees of pairs of adjacent vertices of a simple graph.

Extremal Properties of the Zagreb Eccentricity Indices [PDF]
, 2012 We give sharp lower bounds for the Zagreb eccentricity indices of connected graphs with fixed numbers of vertices and edges, sharp lower and upper bounds for the Zagreb eccentricity indices of trees with fixed number of pendant vertices, sharp upper ...

General multiplicative Zagreb indices of graphs with given clique number [PDF]
, 2019 We obtain lower and upper bounds on general multiplicative Zagreb indices for graphs of given clique number and order. Bounds on the basic multiplicative Zagreb indices and on the multiplicative sum Zagreb index follow from our results. We also determine

On Variable Zagreb Indices [PDF]
, 2004 A novel variant of the Zagreb indices introduced in 1972, called the variable Zagreb indices, is presented. Their performance in the QSPR modeling of lower (C3–C8) alkane boiling points is compared with the original Zagreb indices and their modifications.

On the first and second Zagreb indices of some products of signed graphs
, 2023 Some of the most comprehensively studied degree-based topological indices are the Zagreb indices. In this article, the pair of Zagreb indices have been determined for five product graphs namely tensor product, Cartesian product, lexicographic product ...

ZAGREB CONNECTION INDICES ON POLYOMINO CHAINS AND RANDOM POLYOMINO CHAINS [PDF]
In this manuscript, we delve into the exploration of the first and second Zagreb connection indices of both polyomino chains and random polyomino chains. Our methodology relies on the utilization of Markov chain theory. Within this framework, the article
