ON ARITHMETIC-GEOMETRIC INDEX (GA) AND EDGE GA INDEX
TWMS Journal of Applied and Engineering Mathematics, 2018 Let G (V (G), E(G)) be a simple connected graph and d(G)(u) be the degree of the vertex u. Topological indices are numerical parameters of a graph which are invariant under graph isomorphisms. Recently, people are studying various topological measures such as the arithmetic-geometric index and the edge version of arithmetic geometric index of a graph G.

Conjecture Involving Arithmetic-Geometric and Geometric-Arithmetic Indices
Discrete Dynamics in Nature and Society, 2022 The geometric-arithmetic (GA) index of a graph G is the sum of the ratios of geometric and arithmetic means of end-vertex degrees of edges of G. Similarly, the arithmetic-geometric (AG) index of G is defined. Recently, Vujošević et al. conjectured that a

Fast Reliable Ray-tracing of Procedurally Defined Implicit Surfaces Using Revised Affine Arithmetic [PDF]
, 2009 Fast and reliable rendering of implicit surfaces is an important area in the field of implicit modelling. Direct rendering, namely ray-tracing, is shown to be a suitable technique for obtaining good-quality visualisations of implicit surfaces. We present

Topological Evaluation of Four Para-Line Graphs Absolute Pentacene Graphs Using Topological Indices
International Journal of Analysis and Applications, 2023 A real-number to molecular structure mapping is a topological index. It is a graph invariant method for describing physico-chemical properties of molecular structures specific substances. In that article, We examined pentacene’s chemical composition. The

On the spread of the geometric-arithmetic matrix of graphs
AKCE International Journal of Graphs and Combinatorics, 2022 In a graph G, if di is the degree of a vertex vi, the geometric-arithmetic matrix GA(G) is a square matrix whose [Formula: see text]-th entry is [Formula: see text] whenever vertices i and j are adjacent and 0 otherwise.
