Characterizations of the spectral radius of nonnegative weakly irreducible tensors via digraph

Lizhu Sun, Baodong Zheng, Yimin Wei +1

For a nonnegative weakly irreducible tensor $\mathcal{A}$, we give some characterizations of the spectral radius of $\mathcal{A}$, by using the digraph of tensors. As applications,…
