The isomorphism problem of trees from the viewpoint of Terwilliger algebras

Shuang-Dong Li, Yi-Zheng Fan, Tatsuro Ito +2

Let $Γ^{(x_{0})}$ be a finite rooted tree, for which $Γ$ is the underlying tree and $x_{0}$ the root. Let $T$ be the Terwilliger algebra of $Γ$ with respect to $x_{0}$ . We study the stru…

The least H-eigenvalue of signless Laplacian of non-odd-bipartite hypergraphs

Yi-Zheng Fan, Jiang-Chao Wan, Yi Wang

Let $G$ be a connected non-odd-bipartite hypergraph with even uniformity. The least H-eigenvalue of the signless Laplacian tensor of $G$ is simply called the least eigenvalue of $G…

Eigenvectors of Z-tensors associated with least H-eigenvalue with application to hypergraphs

Yi-Zheng Fan, Yi Wang, Yan-Hong Bao

Unlike an irreducible $Z$ -matrices, a weakly irreducible $Z$ -tensor $A$ can have more than one eigenvector associated with the least H-eigenvalue. We show that there are…
