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…

Weak solutions for weak turbulence models in electrostatic plasmas
Kun Huang, Irene M. Gamba
The weak turbulence model, also known as the quasilinear theory in plasma physics, has been a cornerstone in modeling resonant particle-wave interactions in plasmas. This reduced m…

Exponentially-tailed regularity and time asymptotic for the homogeneous Boltzmann equation
Ricardo Alonso, Irene M. Gamba, Maja TaskoviÄ
We present in this document the Lebesgue and Sobolev propagation of exponential tails for solutions of the homogeneous Boltzmann equation for hard and Maxwell interactions. In addi…
