Abstract
We describe the compact objects in the -category of -valued sheaves on a hypercomplete locally compact Hausdorff space , for a compactly generated stable -category. When is a non-compact connected manifold and is the unbounded derived category of a ring, our result recovers a result of Neeman. Furthermore, for as above and a nontrivial compactly generated stable -category, we show that is compactly generated if and only if is totally disconnected.
