AB  - The topics of this thesis in mathematics belong to the area of operator theory which, in general, studies linear transformations between complete normed vector spaces. Here, all operators considered are bounded and act on complex separable infinite-dimensional Hilbert space. A prototypical example of Hilbert spaces is formed by the square summable sequences of complex numbers. Other common Hilbert spaces consist of functions which are analytic on some open domain of the complex plane. The charac...
