Linear geometries of Baer subspaces
In a finite desarguesian projective space \(PG(d,q^2)\) of square order a subspace of the same dimension \(d\) and of order \(q\) is called a Baer subspace. Each Baer subspace consists of the fixed elements in \(PG(d,q^2)\) of a unique so-called Baer involution. Now the main results of the paper can be stated as follows. Theorem 1.1. Let \(B\) and \(B'\

Differentially Deep Subspace Representation for Unsupervised Change Detection of SAR Images
Temporal analysis of synthetic aperture radar (SAR) time series is a basic and significant issue in the remote sensing field. Change detection as well as other interpretation tasks of SAR images always involves non-linear/non-convex problems.

Convergence Analysis of the Fast Subspace Descent Methods for Convex Optimization Problems
The full approximation storage (FAS) scheme is a widely used multigrid method for nonlinear problems. In this paper, a new framework to design and analyze FAS-like schemes for convex optimization problems is developed.

Blind Reduced-Rank MMSE Detector for DS-CDMA Systems
We first develop a reduced-rank minimum mean squared error (MMSE) detector for direct-sequence (DS) code division multiple access (CDMA) by forcing the linear MMSE detector to lie in a signal subspace of a reduced dimension.
