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 are defined as and $E_2(G)=\sum_{uv\in E(G)}\varepsilon_{G}(u)\var…

Embeddings into almost self-centered graphs of given radius
Kexiang Xu, Haiqiong Liu, Kinkar Ch. Das +1
A graph is almost self-centered (ASC) if all but two of its vertices are central. An almost self-centered graph with radius is called an -ASC graph. The -ASC index $θ_r(G…

Ordering connected graphs by their Kirchhoff indices
Kexiang Xu, Kinkar Ch. Das, Xiao-Dong Zhang
The Kirchhoff index of a graph is the sum of resistance distances between all unordered pairs of vertices, which was introduced by Klein and Randić. In this paper we ch…
