Proxy smallness meets -structures
Michal Hrbek, Pat Lank, Giovanna Le Gros +1
The paper defines proxy smallness for t‑structures on triangulated categories over a Noetherian scheme, using tensor actions, and uses this to characterize locally complete interse…

Detecting derived equivalences with the CHZ criterion
Sergio Pavon
In 2018, Chen, Han and Zhou introduced a criterion to determine whether the HRS-tilt at a given torsion pair induces derived equivalence. We showcase four applications of this crit…

Mutation and the Gabriel spectrum
Michal Hrbek, Sergio Pavon, Jorge Vitória
Mutations occur in multiple algebraic contexts, often enjoying good combinatorial properties. In this paper we study mutations of pure-injective cosilting objects in compactly gene…
