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)
A new a posteriori energy based error estimates were derived. They approximate known estimates but they are more suitable for the two-or multi-level iterative computing algorithms dealing with hierarchical finite element methods. The constants needed for the estimates are computed for the case of p-hierarchical space of piecewise bilinear and biquadratic(More)
