Lemma 47.16.2. Let (A, \mathfrak m, \kappa ) be a Noetherian local ring with normalized dualizing complex \omega _ A^\bullet . Let A \to B be surjective. Then \omega _ B^\bullet = R\mathop{\mathrm{Hom}}\nolimits _ A(B, \omega _ A^\bullet ) is a normalized dualizing complex for B.
Proof. Special case of Lemma 47.16.1. \square
