The Balmer spectrum of a tame stack

Jack Hall

Let $X$ be a quasi-compact algebraic stack with quasi-finite and separated diagonal. We classify the thick $\otimes$ -ideals of $D_{qc} (X)^{c}$ . If $X$ is tame, then…

Coherent Tannaka duality and algebraicity of Hom-stacks

Jack Hall, David Rydh

We establish Tannaka duality for noetherian algebraic stacks with affine stabilizer groups. Our main application is the existence of Hom-stacks in great generality.

Algebraic groups and compact generation of their derived categories of representations

Jack Hall, David Rydh

Let $k$ be a field. We characterize the group schemes $G$ over $k$ , not necessarily affine, such that $D_{qc} (B_{k} G)$ is compactly generated. We also describe the…

One positive and two negative results for derived categories of algebraic stacks

Jack Hall, Amnon Neeman, David Rydh

Let $X$ be a quasi-compact and quasi-separated scheme. There are two fundamental and pervasive facts about the unbounded derived category of $X$ : (1) $D_{qc} (X)$ …

Perfect complexes on algebraic stacks

Jack Hall, David Rydh

We develop a theory of unbounded derived categories of quasi-coherent sheaves on algebraic stacks. In particular, we show that these categories are compactly generated by perfect c…
