Semilinear wave equations in homothetic hyperboloidal coordinates and tail decay
Anıl Zenginoğlu, Sebastiano Bernuzzi, Andrea Nützi
Late-time wave tails decay at different rates along future null infinity and along timelike worldlines at finite radius. A compactified numerical evolution must represent both the…
A Bogovskiǐ-type operator for Corvino-Schoen hyperbolic gluing
Piotr T. Chruściel, Albachiara Cogo, Andrea Nützi
We construct a solution operator for the linearized constant scalar curvature equation at hyperbolic space in space dimension larger than or equal to two. The solution operator has…
Scattering amplitude annihilators
Andrea Nützi, Michael Reiterer
Several second order differential operators are shown to annihilate the YM and GR tree scattering amplitudes. In particular we prove a conjecture of Loebbert, Mojaza and Plefka fro…
Scattering amplitudes in YM and GR as minimal model brackets and their recursive characterization
Andrea Nützi, Michael Reiterer
Attached to both Yang-Mills and General Relativity about Minkowski spacetime are distinguished gauge independent objects known as the on-shell tree scattering amplitudes. We reinte…
