DESCRIPTION:Authors: Jack Coughlin (University of Washington)\, Jingwei Hu
  (University of Washington)\nThe Vlasov-Maxwell-Landau system can provide 
 a high fidelity reproduction of plasma physics\, but only at great computa
 tional cost. Recently\, the dynamical low-rank method has been applied to 
 kinetic simulation of plasmas\, with promising results. The existence of l
 ow-rank structure in asymptotic limits of collisional kinetic equations is
  further motivation for its application to this class of systems. We intro
 duce the dynamical low-rank method and the robust projector-splitting inte
 grator. We then discuss an asymptotic-preserving discretization for the hi
 gh-field limit of the Vlasov-Ampere system\, a simplification of the Vlaso
 v-Maxwell system
