Bounds for Incidence Energy of Some Graphs

الملخص EN

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 incidence matrix.

In this paper, a new upper bound for IE of graphs in terms of the maximum 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.
