The purpose of the paper is to present some convergence properties of the iterative aggregation-disaggregation method for computing a stationary probability distribution vector of a column stochastic matrix. A sufficient condition for the local convergence property and the corresponding rate of convergence are established. Some global convergence(More)
The collection of five papers [2–6] published in this issue of Numerical Linear Algebra with Applications originates from the talks delivered at the conference Preconditioning of Iterative Methods Theory and Applications (PIM 2013), organized in honor of Professor Ivo Marek on the occasion of his 80th birthday and represents a tribute to his work and(More)
