nLab dg-Yoneda embedding


The dg-Yoneda embedding is the analogue of the Yoneda embedding in the setting of dg-categories.


Let dgmod Tdg-mod_T denote the dg-category of dg-modules over TT. The enriched Yoneda embedding is a fully faithful functor of dg-categories

h:Tdgmod T. h : T \hookrightarrow dg-mod_T.

This induces the dg-Yoneda embedding

h:TD(T) h : T \hookrightarrow D(T)

into the derived dg-category of TT, which is a full sub-dg-category of dgmod Tdg-mod_T.
