Forward self-similar solutions to the 2D Navier--Stokes equations
Dallas Albritton, Julien Guillod, Mikhail Korobkov +1
We construct self-similar solutions to the 2D Navier--Stokes equations evolving from arbitrarily large --homogeneous initial data and present numerical evidence for their non-u…
Hyperbolicity of a semi-Lagrangian formulation of the hydrostatic free-surface Euler system
Bernard Di Martino, Chourouk El Hassanieh, Edwige Godlewski +2
By a semi-Lagrangian change of coordinates, the hydrostatic Euler equations describing free-surface sheared flows is rewritten as a system of quasilinear equations, where stability…
Long-time behavior of the Stokes-transport system in a channel
Anne-Laure Dalibard, Julien Guillod, Antoine Leblond
We consider here a two-dimensional incompressible fluid in a periodic channel, whose density is advected by pure transport, and whose velocity is given by the Stokes equation with…
Existence and uniqueness for plane stationary Navier-Stokes flows with compactly supported force
Julien Guillod, Mikhail Korobkov, Xiao Ren
We study the stationary Navier--Stokes equations in the whole plane with a compactly supported force term and with a prescribed constant spatial limit. Prior to this work, existenc…
Nonlinear stability at the Eckhaus boundary
Julien Guillod, Guido Schneider, Peter Wittwer +1
The real Ginzburg-Landau equation possesses a family of spatially periodic equilibria. If the wave number of an equilibrium is strictly below the so called Eckhaus boundary the equ…
Numerical investigations of non-uniqueness for the Navier-Stokes initial value problem in borderline spaces
Julien Guillod, Vladimír Šverák
We consider the Cauchy problem for the incompressible Navier-Stokes equations in for a one-parameter family of explicit scale-invariant axi-symmetric initial data, w…
Existence and uniqueness of steady weak solutions to the Navier-Stokes equations in
Julien Guillod, Peter Wittwer
The existence of weak solutions to the stationary Navier-Stokes equations in the whole plane is proven. This particular geometry was the only case left open since th…

Julien Guillod
The Navier-Stokes equations in a two-dimensional exterior domain are considered. The asymptotic stability of stationary solutions satisfying a general hypothesis is proven under an…
Steady solutions of the Navier-Stokes equations in the plane
Julien Guillod
This study is devoted to the incompressible and stationary Navier-Stokes equations in two-dimensional unbounded domains. First, the main results on the construction of the weak sol…
Optimal asymptotic behavior of the vorticity of a viscous flow past a two-dimensional body
Julien Guillod, Peter Wittwer
The asymptotic behavior of the vorticity for the steady incompressible Navier-Stokes equations in a two-dimensional exterior domain is described in the case where the velocity at i…
On the stationary Navier-Stokes equations in the half-plane
Julien Guillod, Peter Wittwer
We consider the stationary incompressible Navier-Stokes equation in the half-plane with inhomogeneous boundary condition. We prove existence of strong solutions for boundary data c…
Generalized scale-invariant solutions to the two-dimensional stationary Navier-Stokes equations
Julien Guillod, Peter Wittwer
New explicit solutions to the incompressible Navier-Stokes equations in are determined, which generalize the scale-invariant…
