On Relationships between a Linear Matrix Equation and Its Four Reduced Equations
Axioms, 2022 Given the linear matrix equation AXB=C, we partition it into the form A1X11B1+A1X12B2+A2X21B1+A2X22B2=C, and then pre- and post-multiply both sides of the equation by the four orthogonal projectors generated from the coefficient matrices A1, A1, B1, and ...

Constrained Matrix Sylvester Equations [PDF]
SIAM Journal on Matrix Analysis and Applications, 1992 Etant données les matrices \(A(n\times n)\), \(B(n\times p)\), \(C(m\times n)\), \(F((n-m)\times (n-u))\), le problème est de déterminer les matrices \(L((n-m)\times m)\) et \(T((u-m)\times n)\) telles que \(TA-FT=LC\) et \(TB=0\). Les A. établissent des conditions d'existence des solutions ainsi qu'un algorithme de calcul.

Non-commutative NLS-type hierarchies: dressing & solutions [PDF]
, 2019 We consider the generalized matrix non-linear Schrodinger (NLS) hierarchy. By employing the universal Darboux-dressing scheme we derive solutions for the hierarchy of integrable PDEs via solutions of the matrix Gelfand-Levitan-Marchenko equation, and we ...

On Linear Matrix Equations [PDF]
Canadian Mathematical Bulletin, 1980 AbstractSome results from the theory of minimization of vector quadratic forms (subjected to linear restrictions) are used to obtain particular solutions to the usual types of linear matrix equations. An answer to a question raised by Greville [1] is supplied.
