Abstract
In a previous work we constructed the -shaped derived category of any ring for any suitably nice category . The -shaped derived category of , which is denoted by , is a generalization of the ordinary derived category. In this paper we prove that the -shaped derived category of is a compactly generated triangulated category. We also define perfect objects in and prove that these constitute a triangulated subcategory, , of the category of compact objects in the -shaped derived category. The subcategories and coincide if and only if the former is thick.
