Concentrating solutions of the relativistic vlasov-maxwell system
Artikel i vetenskaplig tidskrift, 2019

We study smooth, global-in-time, spherically-symmetric solutions of the relativistic Vlasov-Poisson system that possess arbitrarily large charge densities and electric fields. In particular, we construct solutions that describe a thin shell of equally charged particles concentrating arbitrarily close to the origin and which give rise to charge densities and electric fields as large as one desires at some nite time. We show that these solutions exist even for arbitrarily small initial data or any desired mass. In the latter case, the time at which solutions concentrate can also be made arbitrarily large. As the constructed solutions are spherically-symmetric, they also satisfy the relativistic Vlasov-Maxwell system and thus our results apply to the latter system as well. © 2019 The Author(s).
