Weakly Ding injective complexes
James Gillespie, Alina Iacob
Working over a (left) coherent ring, we consider the class of weakly Ding injective complexes. These are the cycles of the exact complexes of FP-injective complexes that stay exact…

Homological dimensions of complexes over coherent regular rings
James Gillespie, Alina Iacob
We show that Iacob-Iyengar's answer to a question of Avromov-Foxby extends from Noetherian to coherent rings. In particular, a coherent ring R is regular if and only if the injecti…
