Abstract: In this paper, in order to solve nonlinear ill-posed operator equations involving an $m$-accretive mapping on a real Banach space, that does not admit a weak sequential continuous duality mapping, we prove a strongly convergent theorem for Newton–Kantorovich iterative regularization method with a posteriori stopping rule. In our results, the Lipschitz continuity of the derivatives for the mapping is overcomed.

Keywords: accretive and $\alpha$-strong accretive mapping, reflexive Banach space, Fréchet differentiable and the Browder–Tikhonov regularization.
