Varieties Which are almost D ‐Affine

This paper produces several examples of varieties X for which the global sections functor Γ( X ,–): D X ‐ mod → D ( X )‐ mod is exact, and makes D ( X )‐ mod a quotient category of D X ‐ mod , but is not an equivalence. These varieties are quotients by finite group actions of D ‐affine varieties. The torsion of Γ( X ,–) is also described, in some cases. Here, D x ‐ mod denotes the category of quasi‐coherent D X ‐modules.
