Interval B-Tensors and Interval Double B-Tensors
Li Ye, Yisheng Song
This paper systematically investigates the properties and characterization of interval B-tensors and interval double B-tensors. We propose verifiable necessary and sufficient condi…
Positive Definiteness and Stability of Interval Tensors
Li Ye, Yisheng Song
In this paper, we focus on the positive definiteness and Hurwitz stability of interval tensors. First, we introduce auxiliary tensors and establish equivalent condi…
Positive Definiteness of th Order -Dimensional Symmetric Tensors with entries , ,
Li Ye, Yisheng Song
It is well-known that a symmetric matrix with its entries is not positive definite. But this is not ture for symmetric tensors (hyper-matrix). In this paper, we mainly dicus…
Note on "Vacuum stability of a general scalar potential of a few fields"
Yisheng Song
The purpose of this letter is to point out that some conclusions in the paper (Eur. Phys. J. C {\bf 76}, 324(2016)) are incomplete, and to give complete and improved conclusions. T…
