Variation of parabolic cohomology and Poincare duality
Michael Dettweiler, Stefan Wewers
We continue our study of the variation of parabolic cohomology (math.AG/0310139) and derive an exact formula for the underlying Poincare duality. As an illustration of our methods,…

Variation of local systems and parabolic cohomology
Michael Dettweiler, Stefan Wewers
Given a family of local systems on a punctured Riemann sphere, with moving singularities, its first parabolic cohomology is a local system on the base space. We study this situatio…

On the middle convolution
Michael Dettweiler, Stefan Reiter
We present a cohomological interpretation of the middle convolution functor MC and find an explicit Riemann-Hilbert correspondence for MC_λ. This leads to an algorithm for the cons…
