Lower bounds for the low-rank matrix approximation

Journal of Inequalities and Applications, 2017
Low-rank matrix recovery is an active topic drawing the attention of many researchers. It addresses the problem of approximating the observed data matrix by an unknown low-rank matrix. Suppose that A is a low-rank matrix approximation of D, where D and A

Low-x behavior of gluon pseudo- and quasi-PDFs [PDF]

EPJ Web of Conferences, 2022
I will present the formalism one may use to study the behavior of the Ioffe-time distribution at large longitudinal distances and show that the pseudo-PDF and quasi-PDF are very different at low-x.

New Inequalities of Weaving K-Frames in Subspaces

Mathematics, 2019
In the present paper, we obtain some new inequalities for weaving K-frames in subspaces based on the operator methods. The inequalities are associated with a sequence of bounded complex numbers and a parameter λ ∈ R .

Design and Implementation of Pseudo-Inverse Thrust Allocation Algorithm for Ship Dynamic Positioning

IEEE Access, 2020
The pseudo-inverse method cannot optimize the angle and needs to give the azimuth angle artificially, therefore, when the dynamic positioning system has variable vector propellers and rudders, the pseudo-inverse method cannot be applied to the full ...

Some Results on Generalized Inverse of Intuitionistic Fuzzy Matrices

Fuzzy Information and Engineering, 2014
In this paper, pseudo-similar intuitionistic fuzzy matrix (IFM) is defined with some properties of pseudo-similar and semi-similar IFMs studied. Here it is shown that, the pseudo-similarity relation preserve idempotency and regularity for the IFMs. After

Pseudo-inverses of operators [PDF]

Bulletin of the American Mathematical Society, 1974
1. Let X and Y be complex Banach spaces, A a bounded linear operator from X to Y. If the null space N(A) and the closed range R(A)~ possess closed complementary subspaces U in X and V in Y respectively, the pseudo-inverse A* of A relative to (U, V) is defined as the linear extension of (AlU)to D(A*)=R(A)+V With the null space N(A*)=V.

AN INVERSE PROBLEM OF RECOVERING THE RIGHT HAND SIDE OF 1D PSEUDOPARABOLIC EQUATION

Вестник КазНУ. Серия математика, механика, информатика, 2021
Inverse problems of finding the right-hand side of a partial differential equations arise when an external source is unknown or impossible to measurement, for example, the source is in a high-temperature environment or underground.

Frequency-Constrained QR: Signal and Image Reconstruction

Remote Sensing
Because a finite set of measurements is limited in the amount of spectral content it can represent, the reconstruction process from discrete samples is inherently band-limited. In the case of 1D sampling using ideal measurements, the maximum bandwidth of
