摘要

在这项研究中,对于具有r连通分量的图Γ(也适用于连通非二部图和连通二部图),且实数ε≠0,1得到了Γ的拉普拉斯特征值和无符号拉普拉斯特征值ε -幂和的广义和改进界。因此,我们还推广和改进了有关入射能E和拉普拉斯类能不变量L E L的结果。

(Generalized) Incidence and Laplacian-Like Energies
In this study, for graph Γ with r connected components (also for connected nonbipartite and connected bipartite graphs) and a real number ε 0,1 , we found generalized and improved bounds for the sum of ε -th powers of Laplacian and signless Laplacian eigenvalues of Γ . Consequently, we also generalized and improved results on incidence energy I E and Laplacian energy-like invariant L E L .
