偶数阶实对称张量的$H$ -特征值的上下上界

Lower and upper bounds for $H$-eigenvalues of even order real symmetric tensors

Hongwei Jin, M. Rajesh Kannan, Minru Bai

摘要:

在这篇文章中,我们定义了一类新的张量,称为双$\overline{B}$ -张量,准双$\overline{B}$ -张量,并建立了它们的一些性质。利用这些性质,我们构建了新的区域,即,双$\overline{B}$ -区间和拟双$\overline{B}$ -区间,它们包含实偶数阶对称张量的所有$H$ -特征值.证明了双$\overline{B}$ -区间包含在拟双$\overline{B}$ -区间中,拟双${\overline{B}}$ -区间提供了张量的Brauer型特征值包含集的补充信息.这类似于J.M. Pena ~[在另一种Gerschgorin圆和椭圆的卡西尼号,编号。95(2003),第2期,337-345页]。

英文摘要:

In this article, we define new classes of tensors called double $\overline{B}$-tensors, quasi-double $\overline{B}$-tensors and establish some of their properties. Using these properties, we construct new regions viz., double $\overline{B}$-intervals and quasi-double $\overline{B}$-intervals, which contain all the $H$-eigenvalues of real even order symmetric tensors. We prove that the double $\overline{B}$-intervals is contained in the quasi-double $\overline{B}$-intervals and quasi-double ${\overline{B}}$-intervals provide supplement information on the Brauer-type eigenvalues inclusion set of tensors. These are analogous to the double $\overline{B}$-intervals of matrices established by J. M. Peña~[On an alternative to Gerschgorin circles and ovals of Cassini, Numer. Math. 95 (2003), no. 2, 337-345.]
