# How To Make Ext Vanish

@article{Eklof2001HowTM, title={How To Make Ext Vanish}, author={Paul C. Eklof and Jan Trlifaj}, journal={Bulletin of the London Mathematical Society}, year={2001}, volume={33} }

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.

- 2020

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.

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…

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?

- Mathematics
- 2002

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

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)

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…

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…
