给出了张量的一个新的Brauer型特征值局部化集。我们表明,这一套是紧比齐(J.符号计算。2005)、Li等人(Numer. Linear Algebra App. 2014),以及Li and Li(Linear and Multilinear Algebra,2015)。在此基础上,我们给出了非负张量谱半径的一个上界,并证明了这个上界比Yang和Yang(SIAM J. Matrix Anal. App. 2010)和Li等人(Numer. Linear Algebra App.2014)。
A new Brauer-type eigenvalue localization set for tensors is given. We show that this set is tighter than those provided by Qi (J. Symbolic Comput. 2005 ), Li et al. (Numer. Linear Algebra App. 2014), and Li and Li (Linear and Multilinear Algebra, 2015). Based on this set, we give an upper bound for the spectral radius of nonnegative tensors, and prove that the new bound is sharper than those provided by Yang and Yang (SIAM J. Matrix Anal. App. 2010) and Li et al. (Numer. Linear Algebra App. 2014).
