AbstractThe following question was posed by Faith in 1964. Suppose that R is a subring of a matrix ring over a division ring with the property that given any non-zero matrix s there exists an element r in R with rs in R and rs ≠ 0. Do there then exist matrix units {eij} and a left order D in their centralizer such that R contains all matrices in ∑jDelj? The purpose of this article is to provide an affirmative answer
