We study the Jeans instability for a spherically symmetric expanding universe using an exact simulation code. The system, initially submitted to a white noise, breaks into clusters whose size is the smallest wavelength of instability (Jeans length).

We consider two types of transport equations. One with a nonlinear diffusion term and no absorption, the other with a linear diffusion and a nonlinear absorption. Invariance under homothetie transformations leads to the self similar solutions but que

Application of the virial theorem to a Coulomb system of N particles neutralized by a continuous background, leads quite naturally to the definition of a « virial » kinetic pressure for the system of particles, which is fundamentally positive. This

It is shown that the multiple water-bag model, with both analytic and numerical properties, is fairly well suited to the study of forced oscillations launched by grid systems, for different geometries with possible non-uniform charge distribution, an

Using finite group theory, self-similar solutions for the one-dimensional Vlasov– Poisson system are considered, both for electron plasmas, with a fixed ion background, and for a single species beam. Difficulties arising from the Poisson equation a

The author of an article previously appearing in this journal attempted to evaluate the "practical efficacy" of different contraceptive methods, taking failures due to faulty use into account through a study of women requesting abortions. The work su

The basic role played by Coulomb interactions in physics makes them of interest even in one dimension. This explains the effort devoted over the last years to the elucidation of physical properties of some one-dimensional Coulomb systems. Two possibl

Les modèles "multiple Water Bag" (N 20) et "Cauchy d'ordre élevé" (N 12) sont des plus utiles pour calculer les impédances propres et mutuelles de dipôles et quadripôles. Cela vient du fait que le calcul des champs à courte distance implique l

The appearance of a magnetic field perpendicular to the direction of propagation discretizes the continuum spectrum of electrostatic oscillations. For weak magnetic field B this discretization gives linear temporal echoes of shape independent of B an
