The least H-eigenvalue of adjacency tensor of hypergraphs with cut vertices
Yi-Zheng Fan, Zhu Zhu, Yi Wang
Let be a connected hypergraph with even uniformity, which contains cut vertices. Then is the coalescence of two nontrivial connected sub-hypergraphs (called branches) at a…

Eigenvectors of Laplacian or signless Laplacian of Hypergraphs Associated with Zero Eigenvalue
Yi-Zheng Fan, Yi Wang, Yan-Hong Bao +3
Let be a connected -uniform hypergraph. In this paper we mainly consider the eigenvectors of the Laplacian or signless Laplacian tensor of associated with zero eigenvalu…
