Definition 15.90.4. Let $A$ be a ring. Let $K \in D(A)$. Let $I \subset A$ be an ideal. We say $K$ is *derived complete with respect to $I$* if for every $f \in I$ we have $T(K, f) = 0$. If $M$ is an $A$-module, then we say $M$ is *derived complete with respect to $I$* if $M[0] \in D(A)$ is derived complete with respect to $I$.
