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…
