Abstract

We study Tikhonov regularization for certain classes of non-linear ill-posed\noperator equations in Hilbert space. Emphasis is on the case where the solution\nsmoothness fails to have a finite penalty value, as in the preceding study\n'Tikhonov regularization with oversmoothing penalty for non-linear ill-posed\nproblems in Hilbert scales'. Inverse Problems 34(1), 2018, by the same authors.\nOptimal order convergence rates are established for the specific a priori\nparameter choice, as used for the corresponding linear equations.\n
