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 …

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 …

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 …

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

S Crivei, A Kör - Applied Categorical Structures, 2016 - Springer
We introduce and study relative Rickart objects and dual relative Rickart objects in abelian
categories. We show how our theory may be employed in order to study relative regular …

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) …

Weak Rickart and dual weak Rickart objects in abelian categories

S Crivei, D Keskin Tütüncü - Communications in Algebra, 2018 - Taylor & Francis
We introduce and investigate weak relative Rickart objects and dual weak relative Rickart
objects in abelian categories. Several types of abelian categories are characterized in terms …

Torsion and torsion-free classes from objects of finite type in Grothendieck categories

D Bravo, S Odabaşı, CE Parra, MA Pérez - Journal of Algebra, 2022 - Elsevier
In an arbitrary Grothendieck category, we find necessary and sufficient conditions for the
class of FP n-injective objects to be a torsion class. By doing so, we propose a notion of n …

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 …

Equivalences induced by adjoint functors

C Modoi - Communications in Algebra, 2003 - Taylor & Francis
Let 𝒜 and ℬ be two Grothendieck categories, R: 𝒜→ ℬ, L: ℬ→ 𝒜 a pair of adjoint functors,
S∈ ℬ a generator, and U= L (S). U defines a hereditary torsion class in 𝒜, which is carried …
