摘要:

本文介绍了超图的连通性算子,即扩散算子、一般拉普拉斯算子和一般邻接算子。这些算子是超图关联的看似不同的连通矩阵的一些传统概念的推广。事实上,我们在此引入了一个统一框架,用于同时研究超图关联的连通算子的不同变体。计算了与某些类别的超图关联的一般连通算子的特征值和相应的特征空间。从我们新引入的算子的角度研究了诸如超图上的随机游走、动态网络和超图上的疾病传播等应用。我们还推导了超图的弱连通数、顶点度数、最大割、二分宽度和等周常数的谱界。

英文摘要:

Here we introduce connectivity operators, namely, diffusion operators, general Laplacian operators, and general adjacency operators for hypergraphs. These operators are generalisations of some conventional notions of apparently different connectivity matrices associated with hypergraphs. In fact, we introduce here a unified framework for studying different variations of the connectivity operators associated with hypergraphs at the same time. Eigenvalues and corresponding eigenspaces of the general connectivity operators associated with some classes of hypergraphs are computed. Applications such as random walks on hypergraphs, dynamical networks, and disease transmission on hypergraphs are studied from the perspective of our newly introduced operators. We also derive spectral bounds for the weak connectivity number, degree of vertices, maximum cut, bipartition width, and isoperimetric constant of hypergraphs.
