Aggregation-iterative analogues and generalizations of projection-iterative methods

B. A. Shuvar, A. F. Obshta, M. I. Kopach

Abstract


Aggregation-iterative algorithms for linear operator equations are constructed and investigated. These algorithms cover methods of iterative aggregation and projection-iterative methods. In convergence conditions there is neither requirement for the corresponding operator of fixed sign no restriction to the spectral radius to be less than one.

Keywords


Projection-iterative methods, decomposition, aggregation-iterative methods
