Approximation by perfect complexes detects Rouquier dimension

P Lank, N Olander - arXiv preprint arXiv:2401.10146, 2024 - arxiv.org
This work explores bounds on the Rouquier dimension in the bounded derived category of
coherent sheaves on Noetherian schemes. By utilizing approximations, we exhibit that …

Closedness of the singular locus and generation for derived categories

S Dey, P Lank - arXiv preprint arXiv:2403.19564, 2024 - arxiv.org
This work is concerned with a relationship regarding the closedness of the singular locus of
a Noetherian scheme and existence of classical generators in its category of coherent …
