Universal property of triangulated derivators via Keller's towers
Marco Porta
In his thesis B. Keller solved the universal problem of the extension of an exact category to its (bounded) derived category by introducing the notions of tower of exact and triang…
Errata: On the Homology of Completion and Torsion
Marco Porta, Liran Shaul, Amnon Yekutieli
In this note we correct two errors in our paper "On the Homology of Completion and Torsion", arXiv:1010.4386, that appeared in Algebras and Representation Theory (2014).
Cohomologically Cofinite Complexes
Marco Porta, Liran Shaul, Amnon Yekutieli
Let A be a commutative noetherian ring, and \a an ideal in it. In this paper we continue the study, begun in [PSY1], of the derived \a-adic completion and the derived \a-torsion fu…
Completion by Derived Double Centralizer
Marco Porta, Liran Shaul, Amnon Yekutieli
Let A be a commutative ring, and let \a be a weakly proregular ideal in A. (If A is noetherian then any ideal in it is weakly proregular.) Suppose M is a compact generator of the c…
On the Homology of Completion and Torsion
Marco Porta, Liran Shaul, Amnon Yekutieli
Let A be a commutative ring, and \a a weakly proregular ideal in A. This includes the noetherian case: if A is noetherian then any ideal in it is weakly proregular; but there are o…
The Popescu-Gabriel theorem for triangulated categories
Marco Porta
The Popescu-Gabriel theorem states that each Grothendieck abelian category is a localization of a module category. In this paper, we prove an analogue where Grothendieck abelian ca…
