Computing fifth geometric-arithmetic index for nanostar dendrimers
2011The geometric-arithmetic index is a topological index was defined as GA(G)=∑uv2(dudv)1/2/(du+dv), in which degree of vertex u denoted by dG(u ). Now we define a new version of GA index as GA5(G)=∑uv2(δuδv)1/2/(δu+δv) , where δu=∑uvdv. The goal of this paper is to further the study of the GA5 index.

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 ...
