Eccentricity spectral properties of -graphs
Anjitha Ashokan, Chithra A
A cograph is a simple graph that contains no induced path on four vertices. In this paper, we consider -graphs, which are a specific class of cographs, defined as $$\o…

Eccentricity spectrum of join of central graphs and Eccentricity Wiener index of graphs
Anjitha Ashokan, Chithra A
The eccentricity matrix of a simple connected graph is derived from its distance matrix by preserving the largest non-zero distance in each row and column, while the other entries…
