Ill-Posedness of the Hydrostatic Euler and Singular Vlasov Equations
In this paper, we develop an abstract framework to establish ill-posedness, in the sense of Hadamard, for some nonlocal PDEs displaying unbounded unstable spectra. We apply this to prove theExpand

Stability Issues in the Quasineutral Limit of the One-Dimensional Vlasov–Poisson Equation
This work is concerned with the quasineutral limit of the one-dimensional Vlasov–Poisson equation, for initial data close to stationary homogeneous profiles. Our objective is threefold: first, weExpand

On the controllability of the relativistic Vlasov–Maxwell system
In this paper, we study the controllability of the two-dimensional relativistic Vlasov-Maxwell system in a torus, by means of an interior control. We give two types of results. With the geometricExpand

We rigorously establish the asymptotic gyrokinetic limit of the rescaled and modified Vlasov-Poisson system in a three-dimensional setting with the help of an averaging lemma. Expand

Quasineutral Limit of the Vlasov-Poisson System with Massless Electrons
In this paper, we study the quasineutral limit (in other words the limit when the Debye length tends to zero) of Vlasov-Poisson like equations describing the behavior of ions in a plasma. We considerExpand

Effect of the polarization drift in a strongly magnetized plasma
We consider a strongly magnetized plasma described by a Vlasov-Poisson system with a large external magnetic field. The finite Larmor radius scaling allows to describe its behaviour at very fineExpand

Quasineutral limit for Vlasov-Poisson via Wasserstein stability estimates in higher dimension
This work is concerned with the quasineutral limit of the Vlasov-Poisson system in two and three dimensions. We justify the formal limit for very small but rough perturbations of analytic initialExpand

The quasineutral limit of the Vlasov-Poisson equation in Wasserstein metric
In this work, we study the quasineutral limit of the one-dimensional Vlasov-Poisson equation for ions with massless thermalized electrons. We prove new weak-strong stability estimates in theExpand

Geometric Analysis of the Linear Boltzmann Equation I. Trend to Equilibrium
This work is devoted to the analysis of the linear Boltzmann equation on the torus, in the presence of a force deriving from a potential. The collision operator is allowed to be degenerate in theExpand

Asymptotic stability of equilibria for screened Vlasov-Poisson systems via pointwise dispersive estimates
We revisit the proof of Landau damping near stable homogenous equilibria of Vlasov-Poisson systems with screened interactions in the whole space $\mathbb{R}^d$ (for $d\geq3$) that was firstExpand
