The equations AX-YB= C and AX-XB= c in matrices

WE Roth - Proceedings of the American Mathematical Society, 1952 - JSTOR
To do so first consider the elements cci, i= 1, 2,***, a; j= 1, 2,---, f. Equations (6) are evidently
satisfied for every cij where ai and bj are relatively prime. If ai and bj have the greatest …
