Chebyshev acceleration of an alternating Schwarz process. (Russian) Zbl 0697.65019
The author estimates the convergence factor of an alternating Schwarz process with Chebyshev acceleration for the solution of the discretized Poisson equation. By numerical examples he compares the number of iterations needed for the algorithm without acceleration and for the algorithm with Chebyshev acceleration.
