The closure property of H $\mathcal{H}$ -tensors under the Hadamard product
The closure property of H $\mathcal{H}$ -tensors under the Hadamard product
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 …
