WebJan 24, 2024 · We notice that there is a general construction of the derived category of a dg-category $\mathcal{C}$: We first consider the dg-category of right modules over $\mathcal{C}$, which is the dg-category of contravariant dg-functors from $\mathcal{C}$ to Ch$(k)$. Let us denote this dg-category by DGM-$\mathcal{C}$.
