Abstract: We obtain explicit criteria for the isomorphism of formal matrix rings with zero trace ideals. In particular, we consider the case of formal upper-triangular matrix rings with semicentral reduced rings on the principal diagonal.

Keywords: formal matrix ring, upper-triangular ring, semicentral reduced ring, zero trace ideal, isomorphism problem.
