This paper is an improvement of previous results on concentrated Euler flows and their connection with the point vortex model. Precisely, we study the time evolution of an incompressible two dimensional Euler fluid when the initial vorticity is con

We consider a one-species plasma moving in an infinite cylinder in R3, in which it is confined by means of a magnetic field diverging on the walls of the cylinder. In a recent paper [4] we have supposed that the plasma satisfies the Vlasov equation w

We study the time evolution of an incompressible fluid with axial symmetry without swirl, assuming initial data such that the initial vorticity is very concentrated inside $N$ small disjoint rings of thickness $\varepsilon$ and vorticity mass of the

We consider the Vlasov–Poisson equation in [Formula: see text] with initial data which are not [Formula: see text] in space and have unbounded support in the velocities. Assuming for the density a slight decay in space and a strong decay in velocit

We study the screening of a bounded body $$\Gamma $$ against the effect of a wind of charged particles, by means of a shield produced by a magnetic field which becomes infinite on the border of $$\Gamma $$ . The charged wind is modeled by a Vlasov–

We study the existence and uniqueness of the time evolution of a system of infinitely many individuals, moving in a tunnel and subjected to a Cucker-Smale type alignment dynamics with compactly supported communication kernels and to short-range repul

We study existence and uniqueness of the solution to the Vlasov–Poisson system describing a plasma constituted by different species evolving in $${\mathbb {R}}^3$$, whose particles interact via the Coulomb potential. The species can have both posit

We study the time evolution of an incompressible fluid with axial symmetry without swirl when the vorticity is sharply concentrated on $N$ annuli of radii $\approx$ $r_0$ and thickness $\epsilon$. We prove that when $r_0= |\log \epsilon|^\alpha, \,\,

We study the time evolution of a single species positive plasma, confined in a cylinder and having infinite charge. We extend the result of a previous work by the same authors, for a plasma density having compact support in the velocities, to the cas

We discuss the time evolution of a two-dimensional active scalar flow, which extends some properties valid for a two-dimensional incompressible nonviscous fluid. In particular we study some characteristics of the dynamics when the field is initially
