NEW USEFUL ALGORITHMS IN TRANSPORT-THEORY

The aim of this work is to introduce and analyze two new schemes for s olving the transport equations in slab geometry The first one is in th e spirit based on the S.O.R. relaxation method for finite dimensional systems, applied to the system obtained by splitting the collision ope rator The second algorithm is obtained by adaptation of the synthetic diffusion method principle to the new schemes born from the splitting method, Numerical comparisons of convergence are given.
