Jan Gutowski is visiting the Department of Mathematics at King’s College London today (Wednesday 14 February), and giving a talk in the Triangle Seminar Series on “Highly supersymmetric AdS solutions“. Anti-de-Sitter solutions play an important role in the gauge-theory/gravity correspondence, and understanding their properties has provided important insights into the dual field theories. In the talk, Jan considers ADS solutions which are highly supersymmetric, in the sense that they preserve more than 16 supersymmetries, and he shows how modified versions of the homogeneity theorems of Figueroa-O’Farrill, combined with aspects of the global properties of the geometries, can be used to classify these solutions.
