Generalized low rank approximation to the symmetric positive semidefinite matrix

Haixia Chang, Chunmei Li, Qionghui Huang

In this paper, we investigate the generalized low rank approximation to the symmetric positive semidefinite matrix in the Frobenius norm: $$\underset{ rank(X)\leq k}{\min} \sum^m_{…

Inverse eigenproblems and approximation problems for the generalized reflexive and antireflexive matrices with respect to a pair of generalized reflection matrices

Haixia Chang

A matrix $P$ is said to be a nontrivial generalized reflection matrix over the real quaternion algebra $H$ if $P^{*} = P \neq = I$ and $P^{2} = I$ where $*$ means conjugat…

Polytopes of Stochastic Tensors

Haixia Chang, Vehbi E. Paksoy, Fuzhen Zhang

Considering $n \times n \times n$ stochastic tensors $(a_{ij k})$ (i.e., nonnegative hypermatrices in which every sum over one index $i$ , $j$ , or $k$ , is 1), we study the polytope ($Ω…
