摘要：
In this paper, we perform Fourier analysis for a multigrid method with two-cell mu-line relaxation for solving isotropic transport equations. Our numerical results show that the Fourier analysis prediction for convergence rates is more accurate than that previously found by matrix analysis. (C) 1998 Elsevier Science Ltd.
