A Robust Arbitrarily High-Order Transport Method of the Characteristic Type for Unstructured Grids

NUCLEAR SCIENCE AND ENGINEERING, 172(1), 33–51.

TL;DR: A general equivalence between the arbitrary- order neutron balance and arbitrary-order characteristic equations is derived, which improves the numerical computation of the spatial moments of the angular flux and allows a series expansion of the characteristic integral kernel in cases where the medium is optically thin.
