Frequently, problems from natural sciences, technics, or medicine lead to so called inverse problems. In general it means to recover information on parameter of a given model from observable data for instance as in computer tomography. Often these problems can be formulated as seeking a solution of an ill-posed operator equation, that is an operator which do not allow for a continuous inverse.
The lecture will cover the mathematical theory of linear ill-posed problems and will illustrated the phenomenon of "ill posedness" by some examples. We will present regularization methods for ill-posed problems like the Tikhonov regularization. Additionally, some aspects from nonlinear ill-posed problems will be discussed.
Audience
Students of the mathematical programs as from third year, as well as interested students from physics or engineering sciences. The required knowledge from functional analysis will be covered in the lecture as suitable for the audience
