Provides a theoretical convergence guarantee for a known method under weaker conditions, which is incremental for the field of inverse problems.

The paper proves that the iteratively regularized Gauss-Newton method, under a Lipschitz condition and with an a posteriori stopping rule, is an order optimal regularization method for nonlinear ill-posed inverse problems.

In this paper we consider the iteratively regularized Gauss-Newton method for solving nonlinear ill-posed inverse problems. Under merely Lipschitz condition, we prove that this method together with an a posteriori stopping rule defines an order optimal regularization method if the solution is regular in some suitable sense.
