Analytical and computational properties of the variable symmetric division deg index

R. Aguilar-Sanchez, J. A. Mendez-Bermudez, Jose M. Rodriguez +1

The aim of this work is to obtain new inequalities for the variable symmetric division deg index $S D D_{α} (G) = \sum_{uv \in E (G)} (d_{u}^{α} / d_{v}^{α} + d_{v}^{α} / d_{u}^{α})$ , and to characterize grap…

New inequalities involving the Geometric-Arithmetic index

J. M. Rodriguez, J. A. Rodriguez-Velazquez, J. M. Sigarreta

Let $G = (V, E)$ be a simple connected graph and $d_{i}$ be the degree of its $i$ th vertex. In a recent paper [J. Math. Chem. 46 (2009) 1369-1376] the first geometric-arithmetic index o…
