A fast scheme for the homogeneous Boltzmann equation based on lifting and tensor train approximation
Kun Huang, Yingda Cheng, Irene M. Gamba
We propose a fast deterministic scheme for the space-homogeneous Boltzmann equation that exploits the low-rank structure of the velocity distribution. This paper consists of two in…

Entropy-stable positivity-preserving DG schemes for Boltzmann-Poisson models of collisional electronic transport along energy bands
Jose A. Morales Escalante, Irene M. Gamba
This work is related to the development of entropy-stable positivity-preserving DG methods as a computational scheme for Boltzmann-Poisson systems modeling the probability density…
