A cloudy Vlasov solution

A cloudy Vlasov solution

We propose to integrate the Vlasov-Poisson equations giving the evolution of a dynam-ical system in phase-space using a continuous set of local basis functions. In practice, the method decomposes the density in phase-space into small smooth units having compact support. We call these small units " clouds " and choose them to be Gaussians of elliptical support. Fortunately, the evolution of thes...

Cosmological Solution to Einstein-Vlasov System

In this paper the Einstein-Vlasov system of self-consistent field equations is used to construct a cosmological model. A solution is found for a homogeneous isotropic space-time with positive curvature (R × S 3 topology). For the Universe consisting of massless particles the equation for R(t) is solved analytically.

A Finite-Amplitude Solution of the Self-Consistent Vlasov Equations

The paper deals with the propagation of a finite-amplitude circularly polarized electromagnetic plane wave through a fully ionized hot collisionless plasma, composed of Q ( > 1) types of ions and of electrons, as a strict solution of the non-relativistic self-consistent Vlasov equations within the scope of some given applicability criterions. A constant magnetic field and a constant total plasm...

Waves in a Cloudy Vortex

This paper derives a system of equations that approximately govern small-amplitude perturbations in a nonprecipitating cloudy vortex. The cloud coverage can be partial or complete. The model is used to examine moist vortex Rossby wave dynamics analytically and computationally. One example shows that clouds can slow the growth of phase-locked counter-propagating vortex Rossby waves in the eyewal...
