Journal of Mathematical Sciences Aims and scope Submit manuscript

We establish necessary and sufficient conditions for the existence of triangular solutions of a linear matrix equation AX + YB = Cover the commutative ring of principal ideals whose matrix coefficients A, B , and C are triangular matrices. It is also shown that there is no matrix equation of this kind all solutions of which are triangular.
