Regularization of Ill-Posed Problems by Iteration MethodsIteration regularization, i. e., utilization of iteration methods of any form for the stable approximate solution of ill posed problems, is one of the most important but still insufficiently developed topics of the new theory of ill posed problems. In this monograph, a general approach to the justification of iteration regulari zation algorithms is developed, which allows us to consider linear and nonlinear methods from unified positions.
