Wang, Sai; Li, Yuan Some new lower bounds for incidence energy of graphs and extended graph energy. (English) Zbl 1399.05158 Acta Sci. Nat. Univ. Nankaiensis 50, No. 6, 74-78 (2017). Summary: Some new bounds on \({S_\alpha}\) (\({\alpha > 0}\)) are presented, where invariant \({S_\alpha}\) is equal to the sum of powers of signless Laplacian eigenvalues of \(G\). As a result of these bounds, some new results on incidence energy are also obtained. In addition, the extended graph energy is studied.
