• Some Problems Leading to Unbounded Operators.- Hilbert Space Background.- A General Approach to Stabilization.- The Tikhonov-Morozov Method.- Finite-Dimensional Approximations.

From the reviews: "This interesting monograph is devoted to the stable evaluation of the action of unbounded operators defined on Hilbert spaces. This problem is considered as an abstract mathematical problem within the scope of operator approximation theory. To motivate the discussion, the mathematical theory of inverse problems is briefly introduced. ... The monograph is reasonably self-contained and elegantly written. It gradually invites the reader to learn more about the difficulties of solving ill-posed problems." (Antonio C. G. Leitao, Mathematical Reviews, Issue 2008 a) "The author does an excellent job of covering the subject of the title in 120 pages and five chapters ... . the monograph would make a nice graduate course or seminar in applied mathematics." (John R. Cannon, SIAM Review, Vol. 52 (2), 2010)
