We propose an enhanced iterative scheme for the precise reconstruction of piezoelectric material parameters from electric impedance and mechanical displacement measurements. It is based onâ€¦ (More)

In this paper, we study convergence of two different iterative regularization methods for nonlinear ill-posed problems in Banach spaces. One of them is a Landweber type iteration, the other one theâ€¦ (More)

In this paper we investigate the regularizing properties of discretization in preimage space for linear and nonlinear ill-posed operator equations with noisy data. We propose to choose theâ€¦ (More)

We introduce a class of stabilizing Newton-Kaczmarz methods for nonlinear ill-posed problems and analyze their convergence and regularization behaviour. As usual for iterative methods for solvingâ€¦ (More)

Parameter identification problems for partial differential equations (PDEs) often lead to large scale inverse problems. To reduce the computational effort for the repeated solution of the forward andâ€¦ (More)

In this paper a convergence proof is given for the continuous analog of the Gaussâ€”Newton method for nonlinear ill-posed operator equations and convergence rates are obtained. Convergence for exactâ€¦ (More)
