    In the paper under review, the authors provide the derived category analogue of some results about the local cohomology modules. The main result says that: Theorem. Let \(R\) be a commutative Noetherian ring with finite number of maximal ideals. Let \(Z\) be a subset of Spec\((R)\) that is stable under specialization. Then for any left bounded complex \(X\) of \(R\)-modules with finitely generated homology, the following equality holds: \(\mathrm{inf }\{i| H^i_Z (X)\) is not Artinian\(\}=\mathrm{inf }\{\mathrm{depth}_{R_p} X_p| p\in \mathrm{Z-Max }R\}\).
