چکیده
|
The concept of average degree-eccentricity matrix ade(g) of a connected graph g is introduced. some coefficients of the characteristic polynomial of ade(g) are obtained, as well as a bound for the eigenvalues of ade(g). we also introduce the average degree-eccentricity graph energy and establish bounds for it.
