AB - We present an iterative method based on an infinite dimensional adaptation of the
successive overrelaxation (SOR) algorithm for solving the 2-D neutron transport equation.
In a wide range of application, the neutron transport operator admits a Self-Adjoint and
m-Accretive Splitting (SAS). This splitting leads to an ADI-like iterative method which
converges unconditionally and is equivalent to a fixed point problem where the operator is
a 2 by 2 matrix of operators. An infinite dimensional adaptation of a SOR algorithm is
then applied to solve the matrix operator equation. Theoretical and numerical results of
convergence are given
