Engl H.W., Hanke M., Neubauer A. Regularization of Inverse Problems

Kluwer Academic Publishers, 1996, 321 pages.
This book is devoted to the mathematical theory of regularization methods and gives an account of the currently available results about regularization methods for linear and nonlinear ill-posed problems. Both continuous and iterative regularization methods are considered in detail with special emphasis on the development of parameter choice and stopping rules which lead to optimal convergence rates.
