Abstract
AbstractWe consider an iteration method for solving the problem with a complicated positive definite operator A by means of a simpler operator A0 (which inversion is much cheaper than inversion of A). The difference between A and A0 is controlled by some parameter. We prove contraction of the iteration operator and deduce fully computable two– sided a posteriori estimates.
