Let R be a ring, na fixed non-negative integer and n (n) the class of all right (left) R-modules
of FP-injective (flat) dimension at most n. We prove that ( n⊥ n is a perfect cotorsion theory if …

In this article, we study the weak global dimension of coherent rings in terms of the left FP-
injective resolutions of modules. Let R be a left coherent ring and the class of all FP-injective …
