Parallel algorithms for the capacitance matrix method in domain decompositions
The capacitance matrix and its preconditioning matrix associated with domain decomposition by spectral collocation methods for the solution of elliptic problems are characterized. A spectral analysis of the preconditioned capacitance system is carried out and is then applied to the convergence analysis of Richardson and conjugate gradient iterations.
