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…
