本文给出了一类张量的新结果,这类张量是由相应的张量补问题的可解性定义的。对于这类结构张量,我们给出了一个充分条件,保证相应的具有至少两个非零分量的向量的张量互补问题有非零解,并讨论了它们与其它结构张量的关系.进一步,对于具有非负结构张量的张量互补问题,我们得到了其解集的上下界,并证明了结构张量的特征值与解集密切相关.
In this paper, we present some new results on a class of tensors, which are defined by the solvability of the corresponding tensor complementarity problem. For such structured tensors, we give a sufficient condition to guarantee the nonzero solution of the corresponding tensor complementarity problem with a vector containing at least two nonzero components and discuss their relationships with some other structured tensors. Furthermore, with respect to the tensor complementarity problem with a nonnegative such structured tensor, we obtain the upper and lower bounds of its solution set, and by the way, we show that the eigenvalues of such a tensor are closely related to this solution set.
