Abstract
The AN and SPN methods to solve the linear transport equation are rigorously valid for a finite, homoge- neous medium or for heterogeneous, one-dimensional problems. In the present work, two distinct cases are considered, each of them close to one of these situations, and it is shown that the correct equations that take into account for the heterogeneity and the multidimensionality can be obtained by adding suitable extra terms to the model.
