交换图的公共邻域Laplacian谱与无符号Laplacian谱及能量

Common neighborhood Laplacian and signless Laplacian spectra and energies of commuting graphs

Firdous Ee Jannat, Rajat Kanti Nath

AI总结:

针对若干有限非阿贝尔群的交换图,本文计算其公共邻域Laplacian与无符号Laplacian谱及能量,证明整谱性并刻画超能量情形。

摘要:

本文计算了若干有限非阿贝尔群(包括一些AC-群,以及中心商同构于$Sz(2)$、$\mathbb{Z}_p\times \mathbb{Z}_p$或$D_{2m}$的群)的交换图的公共邻域Laplacian谱、公共邻域无符号Laplacian谱及其各自能量。研究结果使我们得出结论:这些图是CNL(CNSL)整谱的。此外,我们刻画了上述群,使其交换图为CNL(CNSL)超能量的。

英文摘要:

In this paper, we compute common neighbourhood Laplacian spectrum, common neighbourhood signless Laplacian spectrum and their respective energies of commuting graph of some finite non-abelian groups including some AC-groups, groups whose central quotients are isomorphic to $Sz(2)$, $\mathbb{Z}_p\times \mathbb{Z}_p$ or $D_{2m}$. Our findings lead us to conclude that these graphs are CNL (CNSL)-integral. Additionally, we characterize the aforementioned groups such that their commuting graphs are CNL (CNSL)-hyperenergetic.
