Low-Rank Tensor Completion and Total Variation Minimization for Color Image Inpainting
IEEE Access, 2020 Low-rank (LR) and total variation (TV) are two most frequent priors that occur in image processing problems, and they have sparked a tremendous amount of researches, particularly for moving from scalar to vector, matrix or even high-order based functions.

Positive semidefinite solution to matrix completion problem and matrix approximation problem
Filomat, 2022 In this paper, firstly, we discuss the following matrix completion problem in the spectral norm: ?(A B B* X)?2 < 1 subject to (A B B* X) ? 0. The feasible condition for the above problem is established, in this case, the general positive semidefinite solution and its minimum rank are presented.

The combinatorially symmetric P-matrix completion problem
The Electronic Journal of Linear Algebra, 1996 An \(n\times n\) real matrix is called a \(P\)-matrix if all its principal minors are positive. The \(P\)-matrix completion problem asks which partial \(P\)-matrices have a completion to a \(P\)-matrix. The authors prove that every partial \(P\)-matrix with combinatorially symmetric specified entries has a \(P\)-matrix completion.
