Randomized Core Reduction for Discrete Ill-Posed Problem
Liping Zhang, Yimin Wei
In this paper, we apply randomized algorithms to approximate the total least squares (TLS) solution of the problem in the large-scale discrete ill-posed problems. A r…
Tensor absolute value equations
Shouqiang Du, Liping Zhang, Chiyu Chen +1
This paper is concerned with solving some structured multi-linear systems, which are called tensor absolute value equations. This kind of absolute value equations is closely relate…
M-tensors and The Positive Definiteness of a Multivariate Form
Liping Zhang, Liqun Qi, Guanglu Zhou
We study M-tensors and various properties of M-tensors are given. Specially, we show that the smallest real eigenvalue of M-tensor is positive corresponding to a nonnegative eigenv…
The Dominant Eigenvalue of an Essentially Nonnegative Tensor
Liping Zhang, Liqun Qi, Ziyan Luo
It is well known that the dominant eigenvalue of a real essentially nonnegative matrix is a convex function of its diagonal entries. This convexity is of practical importance in po…
