The Azumification of orders
Timothy De Deyn
We construct a stacky resolution of singularities for certain noncommutative spaces which can be viewed as `finite noncommutative extensions' of schemes. More precisely, we show th…
Re-framing the classification of ideals in noncommutative tensor triangular geometry
Timothy De Deyn, Sam K. Miller
We prove that a 'pseudo-Hochster dual' of the noncommutative Balmer spectrum of a monoidal triangulated category classifies its semiprime thick tensor ideals. This extends Balmer's…
A note on quasi-perfect morphisms
Timothy De Deyn, Pat Lank, Kabeer Manali Rahul
This note is concerned with quasi-perfect morphisms between Noetherian algebraic spaces. In particular, we study the local behavior of quasi-perfect proper morphisms. We show that…
Categorical characterizations of regularity for algebraic stacks
Timothy De Deyn, Pat Lank, Kabeer Manali Rahul +1
For a Noetherian scheme of finite Krull dimension, Neeman recently established two characterizations of the regularity of using strong generators and bounded -structures…
