Abstract.In computational mathematics and applications, there are numerous examples of problems that are unstable with respect to noise in the input data. Classical numerical algorithms, when used for such problems, turn out to be divergent. Hence, in order to solve the problem in a stable fashion, one has to combine a numerical method with special regularization techniques that would take advantage of an a priori information available in each particular case. In this paper, numerical analysis of Tikhonov's (variational) regularization for a first kind integral equation is given. The regularization parameter is computed by the discrepancy principle of Morozov.
