Aspects of the category SKB of skew braces
D Bourn, A Facchini, M Pompili - Communications in Algebra, 2023 - Taylor & Francis
We examine the pointed protomodular category SKB of left skew braces. We study the
notion of commutator of ideals in a left skew brace. Notice that in the literature,“product” of …

An abstract factorization theorem and some applications
S Tringali - Journal of Algebra, 2022 - Elsevier
We combine the language of monoids with the language of preorders so as to refine some
fundamental aspects of the classical theory of factorization and prove an abstract …

Big pure projective modules over commutative noetherian rings: Comparison with the completion
D Herbera, P Příhoda, R Wiegand - Forum Mathematicum, 2024 - degruyter.com
A module over a ring R is pure projective provided it is isomorphic to a direct summand of a
direct sum of finitely presented modules. We develop tools for the classification of pure …

The realization problem for finitely generated refinement monoids
We show that every finitely generated conical refinement monoid can be represented as the
monoid\mathcal V (R) V (R) of isomorphism classes of finitely generated projective modules …

Kernels of homomorphisms between uniform quasi-injective modules
In this paper, we study the behavior of endomorphism rings of indecomposable (uniform)
quasi-injective modules. A very natural question here is, for a morphism f: A→ B, with A, B …

Galois G-covering of quotients of linear categories
Y Hu, P Zhou - Journal of Pure and Applied Algebra, 2023 - Elsevier
In this paper, we introduce the notion of G-liftable ideals, which extends the liftable ideas
defined by Assem and Le Meur. We characterize the G-liftable ideals and construct the …
