Singularity categories of derived categories of hereditary algebras are derived categories [PDF]

open access: yesJournal of Pure and Applied Algebra, 2020
We show that for the path algebra $A$ of an acyclic quiver, the singularity category of the derived category $\mathsf{D}^{\rm b}(\mathsf{mod}\,A)$ is triangle equivalent to the derived category of the functor category of $\underline{\mathsf{mod}}\,A$, that is, $\mathsf{D}_{\rm sg}(\mathsf{D}^{\rm b}(\mathsf{mod}\,A))\simeq \mathsf{D}^{\rm b}(\mathsf ...

Comparison theorems for Kan, faintly universal and strongly universal derived functors [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
We distinguish between faint, weak, strong and strict localizations of categories at morphism families and show that this framework captures the different types of derived functors that are considered in the literature.

Reflexivity in derived categories [PDF]

open access: yesForum Mathematicum, 2010
An adjoint pair of contravariant functors between abelian categories can be extended to the adjoint pair of their derived functors in the associated derived categories. We describe the reflexive complexes and interpret the achieved results in terms of objects of the initial abelian categories.

Perverse sheaves on Riemann surfaces as Milnor sheaves

open access: yesForum of Mathematics, Sigma, 2023
Constructible sheaves of abelian groups on a stratified space can be equivalently described in terms of representations of the exit-path category. In this work, we provide a similar presentation of the abelian category of perverse sheaves on a stratified

Universal Properties in Quantum Theory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We argue that notions in quantum theory should have universal properties in the sense of category theory. We consider the completely positive trace preserving (CPTP) maps, the basic notion of quantum channel.

How to glue derived categories

open access: yesBulletin of Mathematical Sciences, 2018
We give an overview of existing enhancement techniques for derived and trianguated categories based on the notion of a stable model category, and show how it can be applied to the problem of gluing triangulated categories.

Dualities and derived equivalences for category O [PDF]

open access: yes, 2016
We determine the Ringel duals for all blocks in the parabolic versions of the BGG category O associated to a reductive finite dimensional Lie algebra. In particular we find that, contrary to the original category O and the specific previously known cases

Tilting preserves finite global dimension

open access: yesComptes Rendus. Mathématique, 2020
Given a tilting object of the derived category of an abelian category of finite global dimension, we give (under suitable finiteness conditions) a bound for the global dimension of its endomorphism ring.

Inactivation of indicator microorganisms and biological hazards by standard and/or alternative processing methods in Category 2 and 3 animal by‐products and derived products to be used as organic fertilisers and/or soil improvers

open access: yesEFSA Journal, 2021
The European Commission requested EFSA to assess if different thermal processes achieve a 5 log10 reduction in Enterococcus faecalis or Salmonella Senftenberg (775W) and (if relevant) a 3 log10 reduction in thermoresistant viruses (e.g.
