The importance of being isolated
Scott Balchin, Juan Omar Gómez, Greg Stevenson
We give both a sufficient condition for and an obstruction to the derived category of a commutative ring being generated by its residue fields. As an illustration, we exhibit a rin…
Ore's theorem for thick subcategories
Sira Gratz, Greg Stevenson
We characterize those finite groups for which the bounded derived category of finite dimensional representations over an algebraically closed field of characteristic has distri…
Distributivity, affineness, and the structure sheaf
Andy Jiang, Greg Stevenson
We observe that for a quasi-compact and quasi-separated scheme the structure sheaf generates the perfect complexes if and only if the lattice of thick subcategories is distributive…
Tilting in -shaped derived categories
Sira Gratz, Henrik Holm, Peter Jorgensen +1
The main result of this paper is that there is sometimes a triangulated equivalence between , the -shaped derived category of an algebra , and , the classic…
