摘要
针对张量E-特征值定位问题,利用不等式放缩技巧,给出E-特征值包含集,推广并改进某些已有结果.作为应用,给出弱对称非负张量Z-谱半径的更精确上界.
For locations of E-eigenvalues of tensors,some E-eigenvalue inclusion sets for tensors are obtained by using techniques of inequalities. The result generalizes and improves some known existing results. As an application,a more accurate upper bound for the Z-spectral radius of weakly symmetric nonnegative tensors is obtained.
