Rings whose homomorphic images are<i>q</i>-rings
characterised a commutative noetherian ring in which every proper homomorphic image is self-injective to be a Dedekind domain, or a principal ideal ring with descending chain condition, or a local ring whose maximal ideal M has composition length 2 and satisfies M 2 = 0.The object of this paper is …
