1-4 ON A CLASS OF RATIONALLY COMPLETE RINGS AR MEIJER ABSTRACT: Rings which …

In the present note, we offer a simple characterization of perfect rings in terms of their
components and socle sequences, which is subsequently used to establish a one-to-one …

In this paper we study adjunction relations between some natural functors on the
representation category of the category of finite linearly ordered sets and order-preserving …

1. Introduction and preliminaries. This paper deals with a generalization of the concept of
torsion Abelian groups. Our purpose is twofold. On the one hand, we treat the concept of …

A summary of the key aspects of ideal approximation theory is given, beginning with a
review of the motivating results and arguments from the classical approximation theory. The …

We exploit the equivalence between t-structures and normal torsion theories on a stable
∞∞-category to show how a few classical topics in the theory of triangulated categories, ie …

We prove that if $ R $ is a G-ring then every fully dualizable $ R $-linear cocomplete
category is equivalent to a twist by a $\mathbb {G} _m $-gerbe of the category of modules …

We classify bounded t-structures on the category of perfect complexes over a commutative,
Noetherian ring of finite Krull dimension, extending a result of Alonso Tarrio, Jeremias Lopez …

Let G be a Grothendieck category, let t=(T, F) be a torsion pair in G and let (U t, W t) be the
associated Happel–Reiten–Smalø t-structure in the derived category D (G). We prove that …
