A Predictor-Corrector Strategy for Adaptivity in Dynamical Low-Rank Approximations
Cory Hauck, Stefan Schnake
In this paper, we present a predictor-corrector strategy for constructing rank-adaptive dynamical low-rank approximations (DLRAs) of matrix-valued ODE systems. The strategy is a co…

Asymptotic Preserving Discontinuous Galerkin Methods for a Linear Boltzmann Semiconductor Model
Victor DeCaria, Cory Hauck, Stefan Schnake
A key property of the linear Boltzmann semiconductor model is that as the collision frequency tends to infinity, the phase space density converges to an isotropic fu…
