On the Achievable Level of Accuracy for the Solution of Abstract Ill-Posed Problems and Nonlinear Operator Equations in a Banach Space

It has been shown that, for a wide class of ill–posed problems of finding the value of a discontinuous operator by an approximately specified element in a Banach space, the level of accuracy for the resulting solution cannot be higher in order than the level of error in input data. A similar result...

Zusammenfassung:It has been shown that, for a wide class of ill–posed problems of finding the value of a discontinuous operator by an approximately specified element in a Banach space, the level of accuracy for the resulting solution cannot be higher in order than the level of error in input data. A similar result is established for a class of nonlinear operator equations with an approximate right side. The classes of problems for which these orders are coincident are specified.
