Semi-Bousfield classes and nonmonotone perversities
Dolors Herbera, Michal Hrbek, Giovanna Le Gros
In the generality of a rigidly-compactly generated tensor triangulated category, we introduce semi-Bousfield classes in terms of the vanishing of the tensor product in positive deg…
Trace ideals and uniserial modules
Dolors Herbera, Pavel Pří hoda
We thoroughly investigate the trace ideals of projective modules over the endomorphism ring of a uniserial module. After the work of Dubrovin and Puninski, it is known that this cl…
A family of examples of generalized perfect rings
Pınar Aydoğdu, Dolors Herbera
We construct a family of semiprimitive and non von Neumann regular rings satisfying that any right or left module is isomorphic to a quotient of its flat cover (in the sense of Eno…
Relatively big projective modules and their applications to direct sum decompositions
Román Álvarez, Dolors Herbera, Pavel Příhoda
Countably generated projective modules that are relatively big with respect to a trace ideal were introduced by P. Příhoda, as an extension of Bass' uniformly big projectives. It h…
Cotorsion pairs and Tor-pairs over commutative noetherian rings
Dolors Herbera, Michal Hrbek, Giovanna Le Gros
For a commutative noetherian ring , we classify all the hereditary cotorsion pairs cogenerated by pure-injective modules of finite injective dimension. The classification is don…
A poisonous example to explicit resolutions of unbounded complexes
Dolors Herbera, Wolfgang Pitsch, Manuel Saorín +1
We show that various methods for explicitly building resolutions of unbounded complexes in fact fail when applied to a rather simple and explicit complex. We show that one way to r…
