On minimal edge version of doubly resolving sets of a graph

Muhammad Ahmad, Zohaib Zahid, Sohail Zafar

In this paper, we introduce the edge version of doubly resolving set of a graph which is based on the edge distances of the graph. As a main result, we computed the minimum cardina…

A note on polyomino chains with extremum general sum-connectivity index

Akbar Ali, Tahir Idrees

The general sum-connectivity index of a graph $G$ is defined as $χ_{α} (G) = \sum_{uv \in E (G)} (d_{u} + d_{v})^{α}$ where $d_{u}$ is degree of the vertex $u \in V (G)$ , $α$ is a real number…

On the zeroth-order general Randić index, variable sum exdeg index and trees having vertices with prescribed degree

Sohaib Khalid, Akbar Ali

The zeroth-order general Randić index (usually denoted by $R_{α}^{0}$ ) and variable sum exdeg index (denoted by $S E I_{a}$ ) of a graph $G$ are defined as $R_α^{0}(G)= \sum_{v\in V(G)}…

On the Extremal Graphs with Respect to Bond Incident Degree Indices

Akbar Ali, Darko Dimitrov

Many existing degree based topological indices can be classified as bond incident degree (BID) indices, whose general form is $B I D (G) = \sum_{uv \in E (G)}$ $Ψ (d_{u}, d_{v})$ , where $uv…
