关于$B$ -张量的进一步结果及其在实特征值定位中的应用

Further results on $B$-tensors with application to the location of real eigenvalues

Lu Ye, Zhongming Chen

摘要:

本文对$B$ -张量进行了进一步的研究,并引入了包含$B$ -张量的双$B$ -张量。我们表明,他们有类似的性质,包括他们的分解和严格(双)对角占优张量的强关系。作为应用,利用$B$ -张量的性质,对某些张量的实特征值进行了局部化,这对于证明张量的半正定性是非常有用的。

英文摘要:

In this paper, we give a further study on $B$-tensors and introduce doubly $B$-tensors that contain $B$-tensors. We show that they have similar properties, including their decompositions and strong relationship with strictly (doubly) diagonally dominated tensors. As an application, the properties of $B$-tensors are used to localize real eigenvalues of some tensors, which would be very useful in verifying the positive semi-definiteness of a tensor.
