摘要 研究超图的标号性质,首先利用拉普拉斯张量的第二小和最大特征值给出4一致超图的带宽和与割宽的上下界;其次构造与超图对应的简单图,通过其拉普拉斯矩阵的特征值给出超图带宽的下界. For hypergraphs, several labeling properties are considered. Some upper and lower bounds on the bandwidth sum and cutwidth problems of 4-uniform hypergraphs are derived. These bounds depend on eigenvalues of the Laplacian tensors of hypergraphs. From the corresponding graphs of hypergraphs, a lower bound of the bandwidth is given.
