The complexity of a flat groupoid
Matthieu Romagny, David Rydh, Gabriel Zalamansky
Grothendieck proved that any finite epimorphism of noetherian schemes factors into a finite sequence of effective epimorphisms. We define the complexity of a flat groupoid $R\right…

Mayer-Vietoris squares in algebraic geometry
Jack Hall, David Rydh
We consider various notions of Mayer--Vietoris squares in algebraic geometry. We use these to generalize a number of gluing and pushout results of Moret-Bailly, Ferrand--Raynaud, J…

The telescope conjecture for algebraic stacks
Jack Hall, David Rydh
Using Balmer--Favi's generalized idempotents, we establish the telescope conjecture for many algebraic stacks. Along the way, we classify the thick tensor ideals of perfect complex…
