We study both H and E / Z -eigenvalues of the adjacency tensor of a uniform multi-hypergraph and give conditions for which the largest positive H or Z -eigenvalue corresponds to a strictly positive eigenvector. We also investigate when the E -spectrum of the adjacency tensor is symmetric. Download to read the full article text.

On Spectral Hypergraph Theory of the Adjacency Tensor

WebbThe spectral theory of tensors is an important part of numerical multi-linear algebra, or tensor computation [48, 76, 90]. It is possible that the ideas of eigenvalues of tensors had been raised earlier. However, it was in 2005, the papers of Lim and Qi initiated the rapid developments of the spectral theory of tensors.
