On the construction of Calabi-Yau operators

Stefan Reiter

Given a differential operator of geometric origin there exists a list of operations that preserve this property, e.g., tensor products, pull-backs, push-forwards and the middle con…

On Galois realizations of special linear groups

Michael Dettweiler, Stefan Reiter

We study the determinant of certain etale sheaves constructed via middle convolution in order to realize special linear groups regularly as Galois groups over the rationals.

Monodromy of the Radon transform

Meirav Amram, Michael Dettweiler, Stefan Reiter

We algorithmically determine the monodromy of the local system on the smooth part of the Radon transformation of a generic simple perverse sheaf on the projective plane.

Irregular Hodge numbers for rigid -connections

Konstantin Jakob, Stefan Reiter

Certain rigid irregular -connections constructed by the first-named author are related via pullbacks along a finite covering and Fourier transform to rigid local systems on a…

On the Hodge theory of the additive middle convolution

Michael Dettweiler, Stefan Reiter

We compute the behaviour of Hodge data under additive middle convolution for irreducible variations of polarized complex Hodge structures on punctured complex affine lines.

Monodromy of elliptic curve convolution, seven-point sheaves of -type and motives of Beauville type

Benjamin Collas, Michael Dettweiler, Stefan Reiter +1

We study the Tannakian properties of the category of perverse sheaves on elliptic curves endowed with the convolution product. We establish that for certain sheaves with unipotent…
