On the Freyd categories of an additive category
A Beligiannis - 2000 - projecteuclid.org
To any additive category, we associate in a functorial way two additive categories A (), B ().
The category A (), resp. B (), is the reflection of in the category of additive categories with …

Rickart and dual Rickart objects in abelian categories: Transfer via functors
We study the transfer of (dual) relative Rickart properties via functors between abelian
categories, and we deduce the transfer of (dual) relative Baer property. We also give …

Baer-Kaplansky classes in categories: transfer via functors
S Crivei, DK Tütüncü, R Tribak - Communications in Algebra, 2020 - Taylor & Francis
We study the transfer of Baer-Kaplansky classes via additive functors between preadditive
categories. We show that the Baer-Kaplansky property is well behaved with respect to fully …

Pure-injectivity in the category of flat modules
PAG Asensio, I Herzog - Contemporary Mathematics, 2006 - books.google.com
Let R be an associative ring with identity. A right R-module M is called cotorsion if Ext"(F,
M)= 0 for every flat right R-module F. These modules were introduced by Harrison [21] in the …

[PDF][PDF] On isomorphic injective objects in categories
S Crivei - Mathematical Reports, 2022 - imar.ro
The classical Cantor-Bernstein-Schröder Theorem states that if A and B are two sets such
that there exist injective functions f: A→ B and g: B→ A, then there exists a bijection between …

[PDF][PDF] FTF rings and Frobenius extensions
J Gómez-Torrecillas, B Torrecillas - Journal of Algebra, 2002 - Citeseer
The notion of FTF ring (see Definition 1.1 or Proposition 1.2) captures homological and
finiteness properties shared by several classes of rings. Thus coherent rings with left ffat …

Embeddings of exactly definable and finitely accessible additive categories into Freyd categories
AI Cárceles, JL García - Communications in Algebra, 2009 - Taylor & Francis
Let ℰ be an additive category and 𝒞 a full subcategory with split idempotents, and closed
under isomorphic images and finite direct sums. We give conditions on ℰ and 𝒞 implying …
