On time decay for the spherically symmetric Vlasov-Poisson system

In memory of Robert Glassey

Abstract / Introduction Full Text(HTML) Related Papers Cited by
  • A collisionless plasma is modeled by the Vlasov-Poisson system. Solutions in three space dimensions that have smooth, compactly supported initial data with spherical symmetry are considered. An improved field estimate is presented that is based on decay estimates obtained by Illner and Rein. Then some estimates are presented that ensure only particles with sufficiently small velocity can be found within a certain (time dependent) ball.
