Fourth Geometric Arithmetic Index of Polycyclic Aromatic Hydrocarbons (PAHk)
2016The geometric-arithmetic index of a graph G is defined as . Recently, Ghorbani et. al. introduced the eccentric version of the geometric-arithmetic index as , where is the eccentricity of the vertex u. In this paper, we compute the fourth geometric-version of Polycyclic aromatic hydrocarbons (PAHk).

The First Geometric–Arithmetic Index of Some Nanostar Dendrimers
2014Dendrimers are highly branched organic macromolecules with successive layers or generations of branch units surrounding a central core (1, 4). These are key molecules in nanotechnology and can be put to good use. In this article, we compute the first geometric-arithmetic index of two infinite classes of dendrimers.

THE FIRST GEOMETRIC-ARITHMETIC INDEX OF GRAPH OPERATIONS
2015The first geometric-arithmetic (G-A) index of a graph G is defined as GA(1)(G) = Sigma u(,v is an element of E(G))2 root d(G)(u)d(G)(v)/d(G)(u)+d(G)(v), where d(G)(u) uGd is the degree of the vertex u. Expressions for the first AG. index are obtained for semitotal-line graph (middle graph), semitotal-point graph, total graph as well as eight kinds of ...
