Ekman boundary layers in a domain with topography
Jean-Yves Chemin, Francesco Fanelli, Isabelle Gallagher
We investigate the asymptotic behaviour of fast rotating incompressible fluids with vanishing viscosity, in a {three dimensional} domain with topography including the case of land…
On the radius of analyticity of solutions to semi-linear parabolic systems
Jean-Yves Chemin, Isabelle Gallagher, Ping Zhang
We study the radius of analyticity~ in space, of strong solutions to systems of scale-invariant semi-linear parabolic equations. It is well-known that near the initial time,~…
Some remarks about the possible blow-up for the Navier-Stokes equations
Jean-Yves Chemin, Isabella Gallagher, Ping Zhang
In this work we investigate the question of preventing the three-dimensional, incompressible Navier-Stokes equations from developing singularities, by controlling one component of…
A non linear estimate on the life span of solutions of the three dimensional Navier-Stokes equations
Jean-Yves Chemin, Isabelle Gallagher
The purpose of this article is to establish bounds from below for the life span of regular solutions to the incompressible Navier-Stokes system, whichinvolve norms not only of the…
Tempered distributions and Fourier transform on the Heisenberg group
Hajer Bahouri, Jean-Yves Chemin, Raphael Danchin
The final goal of the present work is to extend the Fourier transform on the Heisenberg group $\H^d,$ to tempered distributions. As in the Euclidean setting, the strategy is to fir…
A Frequency Space for the Heisenberg Group
Hajer Bahouri, Jean-Yves Chemin, Raphael Danchin
We here revisit Fourier analysis on the Heisenberg group H^d. Whereas, according to the standard definition, the Fourier transform of an integrable function f on H^d is a one param…
