Abstract

The distance spectral radius of a connected hypergraph is the largest eigenvalue of its distance matrix. In this paper, we determine the k-uniform hypertree with the minimal spectral radius among all k-uniform hypertrees with m edges and diameter d, where \(3\le d\le m-1\) .

具有固定直径的 k 个均匀肥大树的距离谱半径
摘要 连通超图的距离谱半径是其距离矩阵的最大特征值。在本文中,我们确定了在所有具有 m 条边和直径 d 的 k 个均匀超图中具有最小谱半径的 k 个均匀超图,其中 \(3\le d\le m-1\) .
