Many parallel iterative algorithms for solving symmetric, positive deenite problems proceed by solving in each iteration, a number of independent systems on subspaces. The convergence of such methods is determined by the spectrum of the sums of orthogonal projections on those subspaces, while the convergence of a related sequential method is determined by… CONTINUE READING
