Webb30 juli 2013 · Abstract. 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.
