摘要
循环图是循环群上的Cayley图,整循环图是指其特征值为整数的循环图。图的Sombor能量定义为图的Sombor矩阵的特征值的绝对值之和。借助矩阵理论,以及图的Sombor能量与图的一般能量关系,得到了整循环图的Sombor能量计算的几个公式。
Circulant graphs are Cayley graphs over a cyclic group.A graph is integral if all its eigenvalues are integers.The Sombor energy of a graph is the sum of absolute values of the eigenvalues for its Sombor matrix.In this paper,using matrix theory,and the relationship between the Sombor energy of a graph and its general energy,several formulas for calculating Sombor energy of integral circulant graphs were obtained.
