Transfer of CS-Rickart and dual CS-Rickart properties via functors between abelian categories

S Crivei, SM Radu - Quaestiones Mathematicae, 2022 - Taylor & Francis
We study the transfer of (dual) relative CS-Rickart properties via functors between abelian
categories. We consider fully faithful functors as well as adjoint pairs of functors. We give …

Rickart and dual Rickart objects in abelian categories: Transfer via functors

S Crivei, G Olteanu - Applied Categorical Structures, 2018 - Springer
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 …

CS-Rickart and dual CS-Rickart objects in abelian categories

S Crivei, SM Radu - 2022 - projecteuclid.org
We introduce relative CS-Rickart objects in abelian categories, as common generalizations
of relative Rickart objects and extending objects. We study direct summands and (co) …

Strongly Rickart objects in abelian categories: Applications to strongly regular and strongly Baer objects

S Crivei, G Olteanu - Communications in Algebra, 2018 - Taylor & Francis
We show how the theory of (dual) strongly relative Rickart objects may be employed in order
to study strongly relative regular objects and (dual) strongly relative Baer objects in abelian …

Strongly Rickart objects in abelian categories

S Crivei, G Olteanu - Communications in Algebra, 2018 - Taylor & Francis
We introduce and study (dual) strongly relative Rickart objects in abelian categories. We
prove general properties, we analyze the behaviour with respect to (co) products, and we …

Transfer of splitness with respect to a fully invariant short exact sequence in abelian categories

S Crivei, D Keskin Tütüncü, R Tribak - Communications in Algebra, 2020 - Taylor & Francis
We study the transfer via functors between abelian categories of the (dual) relative splitness
of objects with respect to a fully invariant short exact sequence. We mainly consider fully …

Preserving and reflecting covers by functors. Applications to graded modules

JRG Rozas, B Torrecillas - Journal of Pure and Applied Algebra, 1996 - Elsevier
We study C-covers in the context of Grothendieck categories. Namely, we analyse when a
functor between two Grothendieck categories preserves or reflects C-covers. We apply our …

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 …

Derived categories for Grothendieck categories of enriched functors

G Garkusha, D Jones - Contemp. Math, 2019 - books.google.com
The derived category D [C, V] of the Grothendieck category of enriched functors [C, V], where
V is a closed symmetric monoidal Grothendieck category and C is a small V-category, is …
