Oliver Lindblad Petersen

• I am co-organizing this year's Central European Relativity Seminar, that will take place in Stockholm on May 3-5, 2023. Registration is open here.

I am a researcher and teacher in mathematics with a four years starting grant from the Swedish Research Council (Vetenskapsrådet).

My research is in Geometric Analysis, with emphasis on Mathematical General Relativity. I am particularly interested in:

• Uniqueness of black holes
• Stability of black holes
• Strong cosmic censorship in cosmology
• Stability under Ricci flow

Preprints:

• Non-degenerate Killing horizons in analytic vacuum spacetimes [arXiv]
  (with Klaus Kröncke)
• Analyticity of quasinormal modes in the Kerr and Kerr-de Sitter spacetimes [arXiv]
  (with András Vasy)
• L^p-stability and positive scalar curvature rigidity of Ricci-flat ALE manifolds [arXiv]
  (with Klaus Kröncke)
• Symmetries of vacuum spacetimes with compact Cauchy horizons of constant non-zero surface gravity [arXiv]
  (with I. Rácz)
