In this paper, we investigate the closure property of [Formula: see text]-tensors under the Hadamard product. It is shown that the Hadamard products of Hadamard powers of strong [Formula: see text]-tensors are still strong [Formula: see text]-tensors. We then bound the minimal real eigenvalues of the comparison tensors of the Hadamard products involving strong [Formula: see text]-tensors. Finally, we show how to attain the bounds by characterizing these [Formula: see text]-tensors.
在本文中,我们研究了[公式:见正文]张量在哈达玛积下的封闭性质。结果表明,强[公式:见正文]张量的哈达玛幂的哈达玛积仍是强[公式:见正文]张量。然后,我们对涉及强[公式:见正文]张量的哈达玛积的比较张量的最小实特征值进行了界定。最后,我们通过刻画这些[公式:见正文]张量来说明如何达到这些界。
