Abstract

We prove that, over any ring R, the class of Ding injective modules, (Formula presented.) is the right half of a hereditary cotorsion pair, (Formula presented.) We also show that, over a coherent ring R, a module M is Ding injective if and only if it is Gorenstein injective and in the class (Formula presented.).
