The Non-Classical Boltzmann Equation, and Diffusion-Based Approximations to the Boltzmann Equation

arXiv:1412.1000 · doi:10.1137/140999451

Abstract

We show that several diffusion-based approximations (classical diffusion or SP1, SP2, SP3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be represented exactly by a non-classical transport equation. As a consequence, we indicate a method to solve diffusion-based approximations to the Boltzmann equation via Monte Carlo, with only statistical errors - no truncation errors.
