Limiting absorption principles and linear inviscid damping in the Euler-Boussinesq system in the periodic channel
Michele Coti Zelati, Marc Nualart
We consider the long-time behavior of solutions to the two dimensional non-homogeneous Euler equations under the Boussinesq approximation posed on a periodic channel. We study the…

Diffusion enhancement and Taylor dispersion for rotationally symmetric flows in discs and pipes
Michele Coti Zelati, Michele Dolce, Chia-Chun Lo
In this note, we study the long-time dynamics of passive scalars driven by rotationally symmetric flows. We focus on identifying precise conditions on the velocity field in order t…
