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.

Galois realizations of classical groups and the middle convolution
Michael Dettweiler
We study the middle convolution of local systems on the punctured affine line in the setting of singular cohomology and in the setting of étale cohomology. We derive a formula to c…
