Orbital stability of periodic waves and black solitons in the cubic defocusing NLS equation
TL;DR: In this paper, the first four conserved quantities of the NLS equation were combined to give a direct proof that cnoidal periodic waves are orbitally stable with respect to subharmonic perturbations, with period equal to an integer multiple of the period of the wave.

Thierry Gallay,Geneviève Raugel +1 more
TL;DR: It is proved that the traveling wave is asymptotically stable with respect to perturbations in a weighted Sobolev space and approach a universal self-similar profile, which is independent of $\epsilon$, F, and the initial data.
Long-Time Asymptotics for the Navier-Stokes Equation in a Two-Dimensional Exterior Domain
TL;DR: In this paper, the authors studied the long-time behavior of infinite-energy solutions to the Navier-Stokes equations in a two-dimensional exterior domain, with no-slip boundary conditions.
Interaction des tourbillons dans les écoulements plans faiblement visqueux
TL;DR: In this paper, Navier-Stokes incompressible dans le plan R possède a solution globale unique for toute donnée initiale, quelle que soit la valeur du paramètre de viscosité.
