Query: Twistor structures, tt*-geometry and singularity theory   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 well as classifying spaces of Brieskorn lattices and
(limits of) period maps.
