Parametrizing torsion pairs in derived categories
Lidia Angeleri Hügel, Michal Hrbek
We investigate parametrizations of compactly generated t-structures, or more generally, t-structures with a definable coaisle, in the unbounded derived category D(Mod-A) of a ring…
Telescope conjecture for homotopically smashing t-structures over commutative noetherian rings
Michal Hrbek, Tsutomu Nakamura
We show that any homotopically smashing t-structure in the derived category of a commutative noetherian ring is compactly generated. This generalizes the validity of the telescope…
Countably generated flat modules are quite flat
Michal Hrbek, Leonid Positselski, Alexander Slávik
We prove that if is a commutative Noetherian ring, then every countably generated flat -module is quite flat, i.e., a direct summand of a transfinite extension of localizati…
Definable coaisles over rings of weak global dimension at most one
Silvana Bazzoni, Michal Hrbek
In the setting of the unbounded derived category D(R) of a ring R of weak global dimension at most one we consider t-structures with a definable coaisle. The t-structures among the…
