Characterizations of the spectral radius of nonnegative weakly irreducible tensors via digraph
Lizhu Sun, Baodong Zheng, Yimin Wei +1
For a nonnegative weakly irreducible tensor , we give some characterizations of the spectral radius of , by using the digraph of tensors. As applications,…

Inheritance Properties and Sum-of-Squares Decomposition of Hankel Tensors: Theory and Algorithms
Weiyang Ding, Liqun Qi, Yimin Wei
In this paper, we show that if a lower-order Hankel tensor is positive semi-definite (or positive definite, or negative semi-definite, or negative definite, or SOS), then its assoc…

Inexact Shift-and-Invert Arnoldi for Toeplitz Matrix Exponential
Ting-ting Feng, Gang Wu, Yimin Wei
We revisit the shift-and-invert Arnoldi method proposed in [S. Lee, H. Pang, and H. Sun. {\it Shift-invert Arnoldi approximation to the Toeplitz matrix exponential}, SIAM J. Sci. C…
