Hadamard property of the Unruh state for massless fermions on Kerr spacetime : the large case
Dietrich Häfner, Christiane Klein
In a recent paper by Gérard, Häfner, and Wrochna, the Unruh state for massless fermions on a Kerr spacetime was constructed and the authors showed its Hadmard property in the case…
Mode analysis for the linearized Einstein equations on the Kerr metric : the large case
Lars Andersson, Dietrich Häfner, Bernard F. Whiting
We give a complete analysis of mode solutions for the linearized Einstein equations and the form wave operator on the Kerr metric in the large case. By mode solu…
Scattering theory for Dirac fields inside a Reissner-Nordström-type black hole
Dietrich Häfner, Mokdad Mokdad, Jean-Philippe Nicolas
We show asymptotic completeness for the massive charged Dirac equation between the black hole and Cauchy horizons of a sub-extremal ((Anti-) De Sitter) Reissner-Nordström black hol…
Linear stability of slowly rotating Kerr black holes
Dietrich Häfner, Peter Hintz, András Vasy
We prove the linear stability of slowly rotating Kerr black holes as solutions of the Einstein vacuum equation: linearized perturbations of a Kerr metric decay at an inverse polyno…
Instability of infinitely many stationary solutions of the SU(2) Yang-Mills fields on the exterior of the Schwarzschild black hole
Dietrich Häfner, Cécile Huneau
We consider the spherically symmetric SU(2) Yang-Mills Fields on the Schwarzschild metric. Within the so called purely magnetic Ansatz we show that there exists a countable number…
The decay of the Yang-Mills fields on the Schwarzschild black hole for spherically symmetric small energy initial data
Sari Ghanem, Dietrich Häfner
We prove uniform decay estimates in the entire exterior of the Schwarzschild black hole for gauge invariant norms on the Yang-Mills fields valued in the Lie algebra associated to t…
