Twistor structures, tt*-geometry and singularity theory
Claus Hertling, Christian Sevenheck
We give an overview on the tt*-geometry defined for isolated hypersurface singularities and tame functions via Brieskorn lattices. We discuss nilpotent orbits in this context, as w…

Limits of families of Brieskorn lattices and compactified classifying spaces
Claus Hertling, Christian Sevenheck
We investigate variations of Brieskorn lattices over non-compact parameter spaces, and discuss the corresponding limit objects on the boundary divisor. We study the associated vari…

Linear free divisors and Frobenius manifolds
Ignacio de Gregorio, David Mond, Christian Sevenheck
We study linear functions on fibrations whose central fibre is a linear free divisor. We analyse the Gauss-Manin system associated to these functions, and prove the existence of a…
