Some results on the generalized inverse of tensors and idempotent tensors
Lizhu Sun, Baodong Zheng, Changjiang Bu +1
Let be an order dimension tensor over complex field. In this paper, we study some {generalized inverses} of , the {…
E-cospectral hypergraphs and some hypergraphs determined by their spectra
Changjiang Bu, Jiang Zhou, Yimin Wei
Two -uniform hypergraphs are said to be cospectral (E-cospectral), if their adjacency tensors have the same characteristic polynomial (E-characteristic polynomial). A -unifor…
New rigorous perturbation bounds for the LU and QR factorizations
Hanyu Li, Yimin Wei
Combining the modified matrix-vector equation approach with the technique of Lyapunov majorant function and the Banach fixed point principle, we obtain new rigorous perturbation bo…
Fast Hankel Tensor-Vector Products and Application to Exponential Data Fitting
Weiyang Ding, Liqun Qi, Yimin Wei
This paper is contributed to a fast algorithm for Hankel tensor-vector products. For this purpose, we first discuss a special class of Hankel tensors that can be diagonalized by th…
Perturbation Analysis and Randomized Algorithms for Large-Scale Total Least Squares Problems
Pengpeng Xie, Yimin Wei, Hua Xiang
In this paper, we present perturbation analysis and randomized algorithms for the total least squares (TLS) problems. We derive the perturbation bound and check its sharpness by nu…
