More on energy and Randic energy of specific graphs
Let be a simple graph of order . The energy of the graph is
the sum of the absolute values of the eigenvalues of . The Randi\'{c} matrix
of , denoted by , is defined as the matrix whose
-entry is if and are adjacent and
for another cases. The Randi\'{c} energy of is the sum of absolute
values of the eigenvalues of . In this paper we compute the energy and
Randi\'{c} energy for certain graphs. Also we propose a conjecture on Randi\'c
energy.Comment: 14 page
