公共邻域能量及其与Zagreb指数的关系

Common neighborhood energies and their relations with Zagreb index

Firdous Ee Jannat, Rajat Kanti Nath, Kinkar Chandra Das

AI总结:

本文研究图的公共邻域拉普拉斯能量与第一Zagreb指数的关系,引入CNL-超能量图和CNSL-超能量图概念,证明完全二部图不具备这两种超能量性质,并给出相关能量关系与若干界。

摘要:

本文建立了图的公共邻域拉普拉斯能量和公共邻域无符号拉普拉斯能量与第一Zagreb指数之间的联系。我们引入了CNL-超能量图和CNSL-超能量图的概念,并证明了若$\mathcal{G}$是完全二部图,则$\mathcal{G}$既不是CNL-超能量图也不是CNSL-超能量图。我们得到了图的各种能量之间的若干关系。最后,我们给出了图的公共邻域拉普拉斯能量和无符号拉普拉斯能量的几个界,并以此结束全文。

英文摘要:

In this paper we establish connections between common neighborhood Laplacian and common neighborhood signless Laplacian energies and the first Zagreb index of a graph $\mathcal{G}$. We introduce the concepts of CNL-hyperenergetic and CNSL-hyperenergetic graphs and showed that $\mathcal{G}$ is neither CNL-hyperenergetic nor CNSL-hyperenergetic if $\mathcal{G}$ is a complete bipartite graph. We obtain certain relations between various energies of a graph. Finally, we conclude the paper with several bounds for common neighborhood Laplacian and signless Laplacian energies of a graph.
