A variant of multi-grid method with semi-coarse
For solving systems of linear equations with block tridiagonal matrices there is presenting a variant of multi-grid method with semi-coarse. There are giving the results of numerical experiments, that show high efficiency of presented method.
Optimal parameters and sharp estimates of the convergence rate of the tangent expansion
... problems. Numerical results prove that high convergence rate can be achieved by using these values also for the problems with varying coefficients.
