چکیده
|
Let g be a simple graph. the incidence energy (i e for short) of g is defined as the sum of the singular values of the incidence matrix. in this paper,a new upper bound for i e of graphs in terms of the maximum degree is given. meanwhile,bounds for i e of the line graph of a semiregular graph and the paraline graph of a regular graph are obtained. © 2013 weizhong wang and dong yang.
