On the solvability of linear matrix equations
Mlj Malo Hautus · TU/e Research Portal · 1982
Linear matrix equations were studied by Sylvester, Stephanos, Datuashvili and Roth.In this paper, solvability tz::Onditions given by.these authors are generalized in various directions: to nonsquare equations, nonpolynomial type equations, in particular equations given by an integr~l, and finally to equations over an arbitrary commutative ring with unit element.
