Résume

The unbounded derived category of (right) modules over a ring is a triangulated category with infinite products and coproducts. As a triangulated category with coproducts it is easy to see that it is generated by the projective modules, and similarly it is generated as a triangulated category with products by the injective modules. I will discuss the question of whether it is generated as a triangulated category with coproducts by the injective modules, or as a triangulated category with products by the projective (or flat) modules. I will describe the relationship with the finitistic dimension conjecture, as well as some more recent results.
