Lemma 36.15.1. Let $X$ be a quasi-compact and quasi-separated scheme. Let $U$ be a quasi-compact open subscheme. Let $P$ be a perfect object of $D(\mathcal{O}_ U)$ . Then $P$ is a direct summand of the restriction of a perfect object of $D(\mathcal{O}_ X)$ .

Proof. Special case of Lemma 36.13.11. $\square$
