论文摘要

共光学图是图理论中的一个引人入胜的概念,其中两个非同构图具有相同的特征值集。在本文中,我们计算了$A_α$ - 邻居的特征多项式和非邻居分裂的加入,邻居和非纽布阴影Join,Central Vertex和Edge Join and Edge Join and Repplicate and Replicate of两个图。此外,当$ \ graphene_1 $和$ \ graphene_2 $是常规的时,我们计算这些图的$a_α$ -spectrum。作为一个应用程序,我们构造了非规范的非晶状图,为$a_α$ -cospectral。

Cospectral graphs are a fascinating concept in graph theory, where two non-isomorphic graphs possess identical sets of eigenvalues. In this paper, we compute the $A_α$-characteristic polynomial of neighbour and non-neighbour splitting join, neighbour and non-neighbour shadow join, central vertex and edge join and duplicate join of two graphs. In addition, when $\graphene_1$ and $\graphene_2$ are regular, we compute the $A_α$-spectrum of these graphs. As an application, we construct non-regular, non-isomorphic graphs that are $A_α$-cospectral.
