利用傅里叶变换, 基于群表示和特征标理论显式地给出了双循环群与循环群的直积群上凯莱图的特征值, 建立了该图基尔霍夫指标的闭形公式, 并通过实例说明了所得理论结果的实用性.
By using Fourier transforms and based on group representations and characteristic theory, the eigenvalues of the Cayley graph on the direct product group of double cyclic groups and cyclic groups are explicitly given, and a closed-form formula for the Kirchhoff index of the graph is established. Meanwhile, two examples are presented to illustrate the applicability of our obtained theoretical results.
