Derived Categories of Families of Sextic del Pezzo Surfaces [PDF]

open access: yesInternational mathematics research notices, 2017
We construct a natural semiorthogonal decomposition for the derived category of an arbitrary flat family of sextic del Pezzo surfaces with at worst du Val singularities.

On equivariant derived categories

open access: yesEuropean Journal of Mathematics, 2020
We study the equivariant category associated to a finite group action on the derived category of coherent sheaves of a smooth projective variety. In particular, we discuss decompositions of the equivariant category, prove the existence of a Serre functor,

Parametrizing torsion pairs in derived categories [PDF]

open access: yes, 2019
We investigate parametrizations of compactly generated t-structures, or more generally, t-structures with a definable coaisle, in the unbounded derived category D(Mod-A) of a ring A.

Methoden Komparativer Theologie. Eine Fallstudie im Blick auf das islamische Recht [PDF]

open access: yesAncilla Iuris, 2022
In view of the impossibility of finding neutral categories of comparison, the author pleads for a theological approach to comparative legal research that seeks to shed theological light on the significance of religious law within the respective religion.

Unbounded derived categories and the finitistic dimension conjecture [PDF]

open access: yesAdvances in Mathematics, 2018
We consider the question of whether the injective modules generate the unbounded derived category of a ring as a triangulated category with arbitrary coproducts.

Comparison of miRNA transcriptome of exosomes in three categories of somatic cells with derived iPSCs

open access: yesScientific Data, 2023
Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) through epigenetic manipulation. While the essential role of miRNA in reprogramming and maintaining pluripotency is well studied, little is known about the functions of miRNA ...

The symplectic geometry of higher Auslander algebras: Symmetric products of disks

open access: yesForum of Mathematics, Sigma, 2021
We show that the perfect derived categories of Iyama’s d-dimensional Auslander algebras of type ${\mathbb {A}}$ are equivalent to the partially wrapped Fukaya categories of the d-fold symmetric product of the $2$-dimensional unit disk with finitely many ...

Learning scattering amplitudes by heart

open access: yesPhysics Letters B, 2021
The canonical forms associated to scattering amplitudes of planar Feynman diagrams are interpreted in terms of masses of projectives, defined as the modulus of their central charges, in the hearts of certain t-structures of derived categories of quiver ...

Derived categories of resolutions of cyclic quotient singularities [PDF]

open access: yes, 2017
For a cyclic group $G$ acting on a smooth variety $X$ with only one character occurring in the $G$-equivariant decomposition of the normal bundle of the fixed point locus, we study the derived categories of the orbifold $[X/G]$ and the blow-up resolution

Smoothness of Derived Categories of Algebras [PDF]

open access: yesMoscow Mathematical Journal, 2018
We prove smoothness in the dg sense of the bounded derived category of finitely generated modules over any finite-dimensional algebra over a perfect field, hereby answering a question of Iyama. More generally, we prove this statement for any algebra over
