A Computational Information Criterion for Particle-Tracking with Sparse or Noisy Data
Nhat Thanh Tran, David A. Benson, Michael J. Schmidt +1
Traditional probabilistic methods for the simulation of advection-diffusion equations (ADEs) often overlook the entropic contribution of the discretization, e.g., the number of par…
A toy model for the relativistic Vlasov-Maxwell system
Jonathan Ben-Artzi, Stephen Pankavich, Junyong Zhang
The global-in-time existence of classical solutions to the relativistic Vlasov-Maxwell (RVM) system in three space dimensions remains elusive after nearly four decades of mathemati…
Global Sensitivity Analysis of Plasma Instabilities via Active Subspaces
Stephen Pankavich, Soraya Terrab
Active subspace analysis is a useful computational tool to identify and exploit the most important linear combinations in the space of a model's input parameters. These directions…
Asymptotic Dynamics of Dispersive, Collisionless Plasmas
Stephen Pankavich
A multispecies, collisionless plasma is modeled by the Vlasov-Poisson system. Assuming that the electric field decays with sufficient rapidity as , we show that the ve…
