Abstract Consider an exact category in the sense of Quillen. Assume that in this category every morphism has a kernel and that every kernel is an inflation. In their seminal 1982 paper, Beĭlinson, Bernstein and Deligne consider in this setting a t-structure on the derived category and remark that its heart can be described as a category of formal quotients. They further point out that the category of Banach spaces is an example, and that here a similar category of formal quotients was studied… Expand

A category theoretic approach to extensions of Banach algebras

- Mathematics

This thesis aims to generalise Busby’s framework for studying extensions of C∗-algebras, to the Banach-algebraic setting, without requiring admissibility assumptions on extensions. In the case where… Expand

The left heart and exact hull of an additive regular category

- Mathematics

Quasi-abelian categories are abundant in functional analysis and representation theory. It is known that a quasi-abelian category E is a cotilting torsionfree class of an abelian category. In fact,… Expand

Torsion Pairs and Quasi-abelian Categories

- Mathematics
- 2019

We define torsion pairs for quasi-abelian categories and give several characterisations. We show that many of the torsion theoretic concepts translate from abelian categories to quasi-abelian… Expand

Examples and non-examples of integral categories and the admissible intersection property

- Mathematics
- 2020

Integral categories form a sub-class of pre-abelian categories whose systematic study was initiated by Rump in 2001. In the first part of this article we determine whether several categories of… Expand

In this paper, we study the homological algebra of the category T c of locally convex topological vector spaces from the point of view of derived categories. We start by showing that T c is a… Expand

It is a widespread opinion among experts that (continuous) bounded cohomology cannot be interpreted as a derived functor and that triangulated methods break down. The author proves that this is… Expand

Bivariant (equivariant) K-theory is the standard setting for non- commutative topology. We may carry over various techniques from homotopy theory and homological algebra to this setting. Here we do… Expand

Given a metrizable topological vector space, we can also use its von Neumann bornology or its bornology of precompact subsets to do analysis. We show that the bornological and topological approaches… Expand

This article considers left and right semi-abelian categories in the sense of Rump and establishes characterizations of these notions via six equivalent properties and investigates two examples arising in functional analysis which illustrate that the notions of right and left semi- Isabelian categories are distinct and in particular that such categories occur in nature.
