Lorentzian spectral zeta functions on asymptotically Minkowski spacetimes
Nguyen Viet Dang, Michał Wrochna
In this note, we consider perturbations of Minkowski space as well as more general spacetimes on which the wave operator is essentially self-adjoint. We review a recent…
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…
Propagation of singularities on AdS spacetimes for general boundary conditions and the holographic Hadamard condition
Oran Gannot, Michał Wrochna
We consider the Klein-Gordon equation on asymptotically anti-de Sitter spacetimes subject to Neumann or Robin (or Dirichlet) boundary conditions, and prove propagation of singulari…
The massive Feynman propagator on asymptotically Minkowski spacetimes II
Christian Gérard, Michal Wrochna
We consider the massive Klein-Gordon equation on short-range asymptotically Minkowski spacetimes. Extending our results in [GW1], we show that the Klein-Gordon operator with Feynma…
