The Least Eigenvalue of Graphs

, 2018
In this paper we investigate the least eigenvalue of a graph whose complement is connected, and present a lower bound for the least eigenvalue of such graph.

Seidel energy and its bounds

, 2014
LIU Jian-ping and LIU Bo-lian defined the Seidel energy of the graph G in analog to the definition of the energy of a graph as the sum of the absolute values of the eigenvalues of the Seidel matrix S and analysed for its bounds using the rank of the ...

Minimum covering color energy of a graph

, 2015
In this paper, we introduced the concept of minimum covering color energy EC c (G) of a graph G and computed minimum covering chromatic energies of star graph, complete graph, crown graph, bipartite graph and cocktail graphs.
