On the average lower 2-domination number of a graph
(Işık University Press, 2019)Computer scientists and network scientists want a speedy, reliable, and nonstop communication. In a communication network, the vulnerability measures the resistance of the network to disruption of operation after the failure ... -

Distance spectra of some graph operations and some new distance equienergetic graphs of diameter 3
(Işık University Press, 2019)Two graphs of same order are said to be distance equienergetic if their distance energies are same. In this paper, we first give a partial insight on the distance spectrum of Mycielskian graphs and then we focus on ... -
On the spectra of cycles and paths
(Işık University Press, 2019)Energy of a graph was defined by E. Hückel as the sum of absolute values of the eigenvalues of the adjacency matrix during the search for a method to obtain approximate solutions of Schr¨odinger equation which include the ... -
