Lemma 48.9.6. Let i : Z \to X be a closed immersion of schemes. Assume X is a locally Noetherian. Then R\mathop{\mathcal{H}\! \mathit{om}}\nolimits (\mathcal{O}_ Z, -) maps D^+_{\textit{Coh}}(\mathcal{O}_ X) into D^+_{\textit{Coh}}(\mathcal{O}_ Z).
Proof. The question is local on X, hence we may assume that X is affine. Say X = \mathop{\mathrm{Spec}}(A) and Z = \mathop{\mathrm{Spec}}(B) with A Noetherian and A \to B surjective. In this case, we can apply Lemma 48.9.5 to translate the question into algebra. The corresponding algebra result is a consequence of Dualizing Complexes, Lemma 47.13.4. \square
