Energy Decay in Rindler Spacetime
Anne Franzen, Yafet Sanchez Sanchez
We consider solutions of the massless scalar wave equation on a fixed Rindler background and show polynomial decay of the energy flux related to the Rindler observers n…
Adiabatic Ground States in Non-Smooth Spacetimes
Yafet Sanchez Sanchez, Elmar Schrohe
Ground states are a well-known class of Hadamard states in smooth spacetimes. In this paper we show that the ground state of the Klein-Gordon field in a non-smooth ultrastatic spac…
The Sobolev Wavefront Set of the Causal Propagator in Finite Regularity
Yafet Sanchez Sanchez, Elmar Schrohe
Given a globally hyperbolic spacetime of dimension four and regularity , we estimate the Sobolev wavefront set of the causal propagator of the Kle…
Green operators for low regularity spacetimes
Yafet Sanchez Sanchez, James Vickers
In this paper we define and construct advanced and retarded Green operators for the wave operator on spacetimes with low regularity. In order to do so we require that the spacetime…
Lorentzian surfaces and the curvature of the Schmidt metric
Yafet Sanchez Sanchez, Cesar Merlin, Ricardo Reynoso Fuentes
The b-boundary is a mathematical tool used to attach a topological boundary to incomplete Lorentzian manifolds using a Riemaniann metric called the Schmidt metric on the frame bund…
