On mixed graphs whose Hermitian spectral radii are at most 2
Bo-Jun Yuan, Yi Wang, Shi-Cai Gong +1
A mixed graph is a graph with undirected and directed edges. Guo and Mohar in 2017 determined all mixed graphs whose Hermitian spectral radii are less than . In this paper, we 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 -matrices, a weakly irreducible -tensor can have more than one eigenvector associated with the least H-eigenvalue. We show that there are…
