On irreducibility of eccentricity matrix of graphs and construction of equienergetic graphs
Anjitha Ashokan, Chithra A
The eccentricity matrix , of a connected graph is obtained by retaining the maximum distance from each row and column of the distance matrix of and the other entries…
Resistance distance and Kirchhoff index in central vertex join and central edge join of two graphs
Haritha T, Chithra A
The central graph of a graph is the graph obtained by inserting a new vertex into each edge of exactly once and joining all the non-adjacent vertices in . Let $G_…
On the Adjacency and Seidel Spectra of Hypergraphs
Liya Jess Kurian, Chithra A
A hypergraph generalizes the concept of an ordinary graph. In an ordinary graph, edges connect pairs of vertices, whereas in a hypergraph, hyperedges can connect multiple vertices…
Resistance distance in -coalescence of certain graphs
Haritha T, Chithra A
Any graph can be considered as a network of resistors, each of which has a resistance of The resistance distance between a pair of vertices and in a graph i…
