Quasi-Einstein structures and Hitchin's equations

Alex Colling, Maciej Dunajski

We prove (Theorem 1.1.) that a class of quasi-Einstein structures on closed manifolds must admit a Killing vector field. This extends the rigidity theorem obtained in \cite{DL23} f…

New quasi-Einstein metrics on a two-sphere

Alex Colling, Maciej Dunajski, Hari Kunduri +1

We construct all axi-symmetric non-gradient -quasi-Einstein structures on a two-sphere. This includes the spatial cross-section of the extreme Kerr black hole horizon correspond…
