| چکیده | ||
| Let $R$ be a commutative Noetherian ring, $fa$ an ideal of $R$ and $mathcal{D}(R)$ denote the derived category of $R$-modules. For any homologically bounded complex $X$, we conjecture that $sup {bf L}Lambda^{fa}(X)leq$ mag$_RX$. We prove this in several cases. This generalize the main result of Hatamkhani and Divaani-Aazar cite{HD} for complexes. | ||
