Extremal results on stepwise transmission irregular graphs

Yaser Alizadeh, Sandi Klavžar

The transmission $Tr_{G} (v)$ of a vertex $v$ of a connected graph $G$ is the sum of distances between $v$ and all other vertices in $G$ . $G$ is a stepwise transmission irregula…

On the Relation Between Wiener Index and Eccentricity of a Graph

Hamid Darabi, Yaser Alizadeh, Sandi Klavžar +1

The relation between the Wiener index $W (G)$ and the eccentricity $ε (G)$ of a graph $G$ is studied. Lower and upper bounds on $W (G)$ in terms of $ε (G)$ are prov…

On the difference between the eccentric connectivity index and eccentric distance sum of graphs

Yaser Alizadeh, Sandi Klavžar

The eccentric connectivity index of a graph $G$ is $ξ^{c} (G) = \sum_{v \in V (G)} ε (v) ° (v)$ , and the eccentric distance sum is $ξ^{d} (G) = \sum_{v \in V (G)} ε (v) D (v)$ ,…
