On rotated backwards self-similar solutions of the incompressible 3D Navier-Stokes equations
Ben Pineau, Vlad Vicol
We consider backwards globally self-similar solutions of the 3D incompressible Navier-Stokes equations which are invariant under the joint action of scaling (the natural parabolic…

A Poisson Formula for the Wave Propagator on Schwarzschild-de Sitter Backgrounds
Izak Oltman, Ben Pineau
This paper proposes a Poisson formula for the wave propagator of the Schwarzschild--de Sitter (SdS) metric. That is done by proving a Poisson formula relating wave propagators and…

-Stability for STFT phase retrieval
Susanna Bertolini, Jaume de Dios Pont, Ben Pineau +2
We prove that the short-time Fourier transform with Gaussian window performs -local stable phase retrieval at the constant function. The proof involved significant interplay b…
