Automorphism-invariant modules
Pedro A. Guil Asensio, Ashish K. Srivastava
A module is called automorphism-invariant if it is invariant under any automorphism of its injective envelope. In this survey article we present the current state of art dealing wi…
Modules invariant under automorphisms of their covers and envelopes
Pedro A. Guil Asensio, Derya Keskin Tütüncü, Ashish K. Srivastava
In this paper we develop a general theory of modules which are invariant under automorphisms of their covers and envelopes. When applied to specific cases like injective envelopes,…
Automorphism-invariant modules satisfy the exchange property
Pedro A Guil Asensio, Ashish K. Srivastava
Warfield proved that every injective module has the exchange property. This was generalized by Fuchs who showed that quasi-injective modules satisfy the exchange property. We exten…
A note on the construction of finitely injective modules
Pedro A. Guil Asensio, Manuel C. Izurdiaga, Blas Torrecillas
We develop a technique to construct finitely injective modules which are non trivial, in the sense that they are not direct sums of injective modules. As a consequence, we prove th…
Descent of restricted flat Mittag-Leffler modules and generalized vector bundles
Sergio Estrada, Pedro A. Guil Asensio, Jan Trlifaj
A basic question for any property of quasi--coherent sheaves on a scheme is whether the property is local, that is, it can be defined using any open affine covering of . Loc…
A Lazard-like theorem for quasi-coherent sheaves
Sergio Estrada, Pedro A. Guil Asensio, Sinem Odabasi
We study filtration of quasi--coherent sheaves. We prove a version of Kaplansky Theorem for quasi--coherent sheaves, by using Drinfeld's notion of almost projective module and the…
