Anirban Bhaduri, Timothy De Deyn, Michal Hrbek +2

We show the first instances of schemes whose standard aisles on their derived category of quasi-coherent sheaves are not singly compactly generated.

Classification and nonexistence for $t$ -structures on derived categories of schemes

Alexander Clark, Pat Lank, Kabeer Manali-Rahul +1

Given a suitable Noetherian scheme, we classify tensor $t$ -structures on the bounded derived category of coherent sheaves and its variants with prescribed support. Furthermore, we…
