摘要

In this paper, a new S-type eigenvalue localization set for a tensor is derived by dividing N = { 1 , 2 , … , n } $N={1,2,ldots,n}$ into disjoint subsets S and its complement. It is proved that this new set is sharper than those presented by Qi (J. Symb. Comput. 40:1302-1324, 2005), Li et al. (Numer. Linear Algebra Appl. 21:39-50, 2014) and Li et al. (Linear Algebra Appl. 481:36-53, 2015). As applications of the results, new bounds for the spectral radius of nonnegative tensors and the minimum H-eigenvalue of strong M-tensors are established, and we prove that these bounds are tighter than those obtained by Li et al. (Numer. Linear Algebra Appl. 21:39-50, 2014) and He and Huang (J. Inequal. Appl. 2014:114, 2014).

Symb。Comput。40:1302-1324,2005),Li等人提出的集合更清晰。 (Numer.Linear Algebra Appl.21:39-50,2014)和Li等人。 (Linear Algebra Appl.481:36-53,2015)。作为结果的应用,建立了非负张量谱半径的新界限和强M张量的最小H特征值,并且我们证明这些界限比Li等人获得的界限更严格。 (Numer。Linear Algebra Appl。21:39-50,2014)和He and Huang(J. Inequal。Appl。2014:114,2014)。
