Asymptotic stability of Bernstein-Greene-Kruskal (BGK) waves, Landau Damping, and scattering theory
Ricardo Weder
We consider the two species (electrons and positive charged ions) Vlasov-Poisson system linearized around BGK waves. We formulate the problem as an equivalent Vlasov-Ampère system,…

Galaxy dynamics, gravitational Vlasov-Poisson system, Landau damping, and scattering theory
Ricardo Weder
We consider the gravitational Vlasov-Poisson system linearized around steady states that are extensively used to study the dynamics of galaxies, or of clusters of galaxies. Namely,…
