On the iterative solution of linear operator equations with self-adjoint operators
J. J. Koliha · Journal of the Australian Mathematical Society · 1972
In this paper we deal with a linear equationAu = fin a Hilbert space using a general iterative method with a constant iterative operator for the approximate solution. The method has been studied in many papers [1, 2, 4, 9, 13, 14] and thoroughly treated by Householder [3] for matrix equations and by Petryshyn [7] for operator equations in considerably general and unified manner.
