A study of First geometric-Arithmetic Index with Chemical Applications
Journal Title: Saudi Journal of Engineering and Technology - Year 2017, Vol 2, Issue 7
Abstract
Abstract: The first geometric–arithmetic index 〖GA〗_1 is found to be useful in compute the numerical value of certain graphs and chemical graphs, which is defined as〖GA〗_1=∑_(uv∈E(G))▒(2√(d_u d_v ))/(d_u+d_v ). We denotes d_uthe degree of vertexuinG.In this paper,we present the general formula for the first geometric-Arithmetic Index for certain graphs and k_r-gluing graphs. Keywords: First geometric-Arithmetic Index,k_r-gluing graph, complete graph, Web graph, wheel graph, k-bridge graph.
