一类非负张量谱半径的上下界

Upper and Lower Bounds of Spectral Radius of a Class of Non-negative Tensors

利用张量的有向图,给出一类非负张量谱半径的上界和下界估计,改进了此类非负张量谱半径上下界估计的相应结果.

Using the directed graph of a tensor,the upper and lower bound estimates of the spectral radius of a class of non-negative tensors are given,and the corresponding results of the upper and lower bounds of the spectral radius of such non-negative tensors are improved.
