Homotopy theory of $dg$ categories via localizing pairs and Drinfeld’s $dg$ quotient
Homotopy theory of $dg$ categories via localizing pairs and Drinfeld’s $dg$ quotient
Using localizing pairs and Drinfeld's dg quotient we construct a new Quillen model for the homotopy theory of dg categories.We prove that, in contrast with the original model, this new Quillen model carries a natural closed symmetric monoidal structure.As an application, we obtain a simple construction of the internal Hom-objects …
