Comparison of Wiener index and Zagreb eccentricity indices

Kexiang Xu, Kinkar Chandra Das, Sandi Klavžar +1

The first and the second Zagreb eccentricity index of a graph $G$ are defined as $E_{1} (G) = \sum_{v \in V (G)} ε_{G} (v)^{2}$ and $E_2(G)=\sum_{uv\in E(G)}\varepsilon_{G}(u)\var…

Comparing Wiener complexity with eccentric complexity

Kexiang Xu, Aleksandar Ilić, Vesna Iršič +2

The transmission of a vertex $v$ of a graph $G$ is the sum of distances from $v$ to all the other vertices in $G$ . The Wiener complexity of $G$ is the number of different transmiss…
