Note on the Sum of Powers of Signless Laplacian Eigenvalues of Graphs

Ş. Burcu Bozkurt Altındağ, Durmuş Bozkurt

For a simple graph $G$ and a real number $\alpha$ $\left(\alpha \ne 0,1\right)$ the graph invariant $s_{\alpha }\left(G\right)$ is equal to the sum of powers of signless Laplacian eigenvalues of $…
