CNRS Research Director, visiting IHES

Jérémie Szeftel, CNRS Research Director at the Jacques-Louis Lions Laboratory of Sorbonne University, specializes in nonlinear partial differential equations, and more particularly in the equations of general relativity and the phenomenon of finite time explosion.

His collaboration with Sergiu Klainerman and Igor Rodnianski led to the solution of the L2 curvature conjecture in general relativity. 

His recent results are about:

  • the resolution of the Kerr black hole stability conjecture in the special case of weakly rotating black holes, which he did in collaboration with Sergiu Klainerman, and in part with Elena Giorgi and Dawei Shen;
  • the description of explosive regimes for the nonlinear supercritical focusing Schrödinger equation and for compressible fluids, done in collaboration with Frank Merle, Pierre Raphaël, and Igor Rodnianski.
