ANR ScattHoloGR
Scattering, Holography and General Relativity
January 2025 - December 2029

The main purpose of this project is the systematic development of scattering theory in general relativity using conformal and projective geometrical methods. Our work programme includes the following directions:

  • Conformal scattering for massless fields, linear and non linear;
  • Projective scattering for massive fields;
  • Inverse scattering by geometrical methods;
  • Relations between peeling, scattering and asymptotic charges
  • Numerical simulation of a scattering process on a compactified spacetime;
  • Development of SageManifolds and in particular addition of spinor calculus.

News and events
Post-doc offer

We are looking for an expert in the asymptotic analysis of partial differential equations, ideally with a working experience in general relativity, for a two-year post-doc position at Institut Denis Poisson (Tours, UMR 7013), starting in Autumn 2026. The appointed person will collaborate with Yannick Herfray (IDP, Tours) and Jean-Philippe Nicolas (LMBA, Brest) as part of the ANR project ScattHoloGR (Scattering, Holography and General Relativity). The main purpose of the programme is to develop the geometric approach to scattering theory and to understand the peeling phenomenon, in relation with asymptotic symmetries.
