Twistor structures, tt*-geometry and singularity theory

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/164865We 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.to appear in "From tQFT to tt* and integrability", Proceedings of Symposia in Pure Mathematics, AMSAlgebraic GeometryComplex VariablesDifferential Geometry14D07, 32S30, 32S40, 53C07, 32G20Twistor structures, tt*-geometry and singularity theorytext
