Jack Borthwick, Nabile Boussaïd, Thierry Daudé
In this paper, we study a new type of inverse problem on warped product Riemannian manifolds with connected boundary that we name warped balls. Using the symmetry of the geometry,…

Scattering theory for Dirac fields near an extreme Kerr-de Sitter black hole
Jack Borthwick
In this paper, we construct a scattering theory for classical massive Dirac fields near the "double" horizon of an extreme Kerr-de Sitter blackhole. Our main tool is the existence…
