Speaker: Klaus Widmayer(University of Zurich


Title: On the stability of a point charge for the Vlasov-Poisson system


Abstract: A Dirac mass is a particularly simple yet relevant equilibrium of the (repulsive) Vlasov-Poisson equations. This talk addresses the question of its stability in the repulsive setting: we capture the precise asymptotic dynamics of solutions which start as small, smooth and suitably localized perturbations of a point charge. Our analysis builds on the Hamiltonian/symplectic structure of the equations, and makes use of an exact integration of the linearized equation through angle-action coordinates. This allows us to obtain optimal decay estimates and reveals a modified scattering dynamic.


This is joint work with Jiaqi Yang (ICERM) and Benoit Pausader (Brown University).
