Iteratively regularized Landweber iteration method: Convergence analysis via Hölder stability

作者:

Highlights:

• In this paper, the local convergence of Iteratively regularized Landweber iteration method is investigated for solving non-linear ill-posed inverse problems in Banach spaces.

• The convergence analysis is based on a recently discovered smoothness concept of Holder stability estimates.

• We discussed the convergence analysis for both the noisy as well as non-noisy data.

• The assumptions in the paper are verified through a concrete example.

• The study provides two different convergence rates for the iterates.
