On the spectrum of discrete-ordinates neutron transport problems
Brazilian Journal of Radiation Sciences, 2021 Over the last six decades, the discrete spectrum of the neutron transport operator has been widely studied. Important theoretical results can be found in the literature regarding the one-speed linear transport equation with anisotropic scattering.

Goal-oriented multi-collision source algorithm for discrete ordinates transport calculation
Nuclear Engineering and Technology, 2022 Discretization errors are extremely challenging conundrums of discrete ordinates calculations for radiation transport problems with void regions. In previous work, we have presented a multi-collision source method (MCS) to overcome discretization errors,

ANALYTIC DISCRETE-ORDINATES SOLUTION FOR TIME-DEPENDENT TRANSPORT IN FINITE MEDIA [PDF]
EPJ Web of Conferences, 2021 We present an extension of the Analytic Discrete-Ordinates method to time-dependent transport in finite media. The application of this technique to time-dependent transport is primarily accomplished through the use of a Laplace transform.

Sparse Discrete Ordinates Method in Radiative Transfer [PDF]
Computational Methods in Applied Mathematics, 2011 AbstractThe stationary monochromatic radiative transfer equation (RTE) is a partial differential transport equation stated on a five-dimensional phase space, the Cartesian product of physical and angular domain. We solve the RTE with a Galerkin FEM in physical space and collocation in angle, corresponding to a discrete ordinates method (DOM)
