Abstract
The study of graphs containing edges and nodes is of great importance in science and in real life. Topological indices <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M3"> <a:mfenced open="(" close=")"> <a:mrow> <a:mtext>TIs</a:mtext> </a:mrow> </a:mfenced> </a:math> are numerical parameters linked to chemical graphs used to estimate the biological, toxicological, and physical properties of chemical compounds. Recently, two terms, ev-degree- and ve-degree-based TIs, have been defined in chemical graph theory. In this paper, we have estimated degree-based TIs, namely, ev-degree Zagreb <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M4"> <e:mfenced open="(" close=")"> <e:mrow> <e:mtext>M</e:mtext> </e:mrow> </e:mfenced> </e:math> type index, ev-degree Randic <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" id="M5"> <i:mfenced open="(" close=")"> <i:mrow> <i:mtext>R</i:mtext> </i:mrow> </i:mfenced> </i:math> index, ve-degree atom-bond connectivity <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" id="M6"> <m:mfenced open="(" close=")"> <m:mrow> <m:mtext>ABC</m:mtext> </m:mrow> </m:mfenced> </m:math> index, ve-degree geometric arithmetic index <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" id="M7"> <q:mfenced open="(" close=")"> <q:mrow> <q:mtext>GA</q:mtext> </q:mrow> </q:mfenced> </q:math> , ve-degree harmonic <u:math xmlns:u="http://www.w3.org/1998/Math/MathML" id="M8"> <u:mfenced open="(" close=")"> <u:mrow> <u:mtext>H</u:mtext> </u:mrow> </u:mfenced> </u:math> index, and ve-degree sum-connectivity index for <y:math xmlns:y="http://www.w3.org/1998/Math/MathML" id="M9"> <y:mtext>Si</y:mtext> <y:msub> <y:mrow> <y:mtext>C</y:mtext> </y:mrow> <y:mrow> <y:mn>4</y:mn> </y:mrow> </y:msub> </y:math> - <ab:math xmlns:ab="http://www.w3.org/1998/Math/MathML" id="M10"> <ab:mtext>II</ab:mtext> <ab:mfenced open="[" close="]"> <ab:mrow> <ab:mi>i</ab:mi> <ab:mo>,</ab:mo> <ab:mi>j</ab:mi> </ab:mrow> </ab:mfenced> </ab:math> .
