Asymptotic--preserving and energy stable dynamical low-rank approximation
Lukas Einkemmer, Jingwei Hu, Jonas Kusch
Radiation transport problems are posed in a high-dimensional phase space, limiting the use of finely resolved numerical simulations. An emerging tool to efficiently reduce computat…

Efficient dynamical low-rank approximation for the Vlasov-Ampère-Fokker-Planck system
Jack Coughlin, Jingwei Hu
Kinetic equations are difficult to solve numerically due to their high dimensionality. A promising approach for reducing computational cost is the dynamical low-rank algorithm, whi…
