Complex powers of the wave operator and the spectral action on Lorentzian scattering spaces
Nguyen Viet Dang, Michał Wrochna
We consider perturbations of Minkowski space as well as more general spacetimes on which the wave operator is known to be essentially self-adjoint. We define complex po…

The Unruh state for massless fermions on Kerr spacetime and its Hadamard property
Christian Gérard, Dietrich Häfner, Michał Wrochna
We give a rigorous definition of the Unruh state in the setting of massless Dirac fields on slowly rotating Kerr spacetimes. In the black hole exterior region, we show that it is a…

The Feynman problem for the Klein-Gordon equation
Christian Gérard, Michał Wrochna
We report on the well-posedness of the Feynman problem for the Klein-Gordon equation on asymptotically Minkowski spacetimes. The main result is the invertibility of the Klein-Gordo…
