TCS-GAP Seminar: “Quasi-Einstein metrics”

The online Trans-Carpathian Seminar on Geometry & Physics (TGA)

Quasi-Einstein metrics
Prof. Dr. Maciej Dunajski (University of Cambridge)

DATE: Wednesday, May 22, 2024, 15:15 EET (Bucharest time)

ABSTRACT: “We prove that the intrinsic Riemannian geometry of compact cross-sections of any Einstein extremal horizon must admit a Killing vector field. This establishes the rigidity theorem for the extremal Kerr black hole horizon. This extremal horizon is a special case of a quasi-Einstein structure. We shall discuss other examples of quasi-Einstein structures on compact surfaces, including a global result relevant in projective metrizability.”
