Bounds for Incidence Energy of Some Graphs.

Let G be a simple graph. The incidence energy (IE for short) of G is defined as the sum of the singular values of the incidencematrix. In this paper, a new upper bound for IE of graphs in terms of themaximum degree is given. Meanwhile, bounds for IE of the line graph of a semiregular graph and the paraline graph of a regular graph are obtained. [ABSTRACT FROM AUTHOR]
