Acknowledgements I would like to express my gratitude to my advisor, Manuel Saorín Castaño, whose presence and help have been decisive to carry out this work. I am grateful to K. Fuller for pointing out some references used in Example 2.6.2, to K. Goodearl for telling us about key results in [37, 100] used in Chapter 3, and to J. Trlifaj for suggesting Lemma 6.3.14 and Example 6.3.15. Also, I am grateful to B. Keller for carefully reading the manuscript of [85], for several conversations and e-mail exchange concerning dg categories, for his supervision of [81] and for his extremely kind hospitality during my stays in Paris.

A TTF-triple (C, T , F) in an abelian category is one-sided split in case either (C, T) or (T , F) is a split torsion theory. In this paper we classify one-sided split TTF-triples in module categories, thus completing Jans' classification of two-sided split TTF-triples and answering a question that has remained open for almost forty years.
متن کاملOn Topological Filtration for Triquaternion Algebra
The topological filtration on the Grothendieck group of the Severi-Brauer variety corresponding to a triquaternion algebra is computed. In particular, it is shown that the second Chow group of the variety is torsionfree. Let F be a field, A a central simple F -algebra of degree 8 and exponent 2, X = SB(A) the Severi-Brauer variety of A [2]. Consider the second Chow group CH(X), i.e. the group o...
متن کاملRanks of modules relative to a torsion theory
Relative to a hereditary torsion theory $tau$ we introduce a dimension for a module $M$, called {em $tau$-rank of} $M$, which coincides with the reduced rank of $M$ whenever $tau$ is the Goldie torsion theory. It is shown that the $tau$-rank of $M$ is measured by the length of certain decompositions of the $tau$-injective hull of $M$. Moreover, some relations between the $tau$-rank of $M$ and c...
متن کاملTorsion Z-module and Torsion-free Z-module1
In this article, we formalize a torsion Z-module and a torsionfree Z-module. Especially, we prove formally that finitely generated torsion-free Z-modules are finite rank free. We also formalize properties related to rank of finite rank free Z-modules. The notion of Z-module is necessary for solving lattice problems, LLL (Lenstra, Lenstra, and Lovász) base reduction algorithm [20], cryptographic...
متن کاملAlmost uniserial modules
An R-module M is called Almost uniserial module, if any two non-isomorphic submodules of M are linearly ordered by inclusion. In this paper, we investigate some properties of Almost uniserial modules. We show that every finitely generated Almost uniserial module over a Noetherian ring, is torsion or torsionfree. Also the construction of a torsion Almost uniserial modules whose first nonzero Fit...
