We describe a general construction of a module A from a given module B such that Ext(B, A) = 0, and we apply it to answer several questions on splitters, cotorsion theories and saturated rings.

Continuous limits of tilting modules
A constructive argument is provided to obtain an infinite generated tilting module from a family of  tilting modules satisfying some  hypotheses and the result is applied over a hereditary algebra to get the Lukas Tilting module.
Relative Nonhomogeneous Koszul Duality
All the constructions of Chapters 1-10 can be carried out with the category of k-modules replaced by the category of graded k-modules.
ON THE EXISTENCE OF FLAT COVERS IN R-gr
• Mathematics
• 2001
Recently, a proof of the existence of a flat cover of any module over an arbitrary associative ring with unit has been finally given (see 4-5). In this paper we prove the existence of flat covers in
FI -Injective Resolutions and Dimensions
In this paper, we show the existence of FI-injective preenvelopes over coherent rings, characterize FI-injective resolutions and define FIinjective dimension for modules and rings. It measures how
Bounded complexes of cotorsion sheaves
ABSTRACT We provide a necessary and suﬃcient condition which ensure that every flat quasi-coherent sheaf has finite cotorsion dimension. Also, we will show that every locally noetherian scheme with a
WHEN ARE PURE-INJECTIVE ENVELOPES OF FLAT MODULES FLAT?
ABSTRACT The question is answered in terms of flat covers, flat cotorsion modules, and cotorsion envelopes. It is shown that the corresponding class of rings properly contains that of coherent rings.
One Dimensional Tilting Modules are of Finite Type
• Mathematics
• 2008
We prove that every tilting module of projective dimension at most one is of finite type, namely that its associated tilting class is the Ext-orthogonal of a family of finitely presented modules of
A note on tilting sequences
• Mathematics
• 2008
We discuss the existence of tilting modules which are direct limits of finitely generated tilting modules over tilted algebras.
All Modules Have Gorenstein Flat Precovers

It is shown in the paper that every R-module has a Gorenstein flat precover.
Cotorsion pairs and model structures on Ch(R)
• Mathematics
Proceedings of the Edinburgh Mathematical Society
• 2011
Abstract We show that if the given cotorsion pair $(\mathcal{A},\mathcal{B})$ in the category of modules is complete and hereditary, then both of the induced cotorsion pairs in the category of

Injective and flat covers, envelopes and resolvents
Using the dual of a categorical definition of an injective envelope, injective covers can be defined. For a ringR, every leftR-module is shown to have an injective cover if and only ifR is left

Let R be a subring of the rationals. We want to investigate self splitting R-modules G that is Ext_R(G,G)=0 holds. For simplicity we will call such modules splitters. Our investigation continues
