超图的张量连接及其谱

Tensor join of hypergraphs and its spectra

R. Vishnupriya, R. Rajkumar

AI总结:

本文提出超图的张量连接运算,证明任意超图可表示为张量连接,并计算其邻接、拉普拉斯及归一化拉普拉斯谱,进而构造多类同谱超图。

摘要:

本文利用张量引入了超图上的三种运算。我们证明这三种构造是等价的,并将其统称为张量连接。我们证明任意超图都可以视为若干超图的张量连接。张量连接使我们能够得到超图上若干已有和新的运算类。我们计算了由该张量连接构造的加权超图的邻接谱、拉普拉斯谱和归一化拉普拉斯谱。同时,我们推导了文献中关于超图谱的一些结果。作为应用,我们利用张量连接构造了若干对邻接、拉普拉斯和归一化拉普拉斯同谱超图。

英文摘要:

In this paper, we introduce three operations on hypergraphs by using tensors. We show that these three formulations are equivalent and we commonly call them as the tensor join. We show that any hypergraph can be viewed as a tensor join of hypergraphs. Tensor join enable us to obtain several existing and new classes of operations on hypergraphs. We compute the adjacency, the Laplacian, the normalized Laplacian spectrum of weighted hypergraphs constructed by this tensor join. Also we deduce some results on the spectra of hypergraphs in the literature. As an application, we construct several pairs of the adjacency, the Laplacian, the normalized Laplacian cospectral hypergraphs by using the tensor join.
