Publications

As my employer’s full text server offers the user dialogue only in German, I am providing links here to select publications of my group. These files are hosted on the university’s server with permission of the respective publishers, or are in the public domain. In the former case, please observe the copyright restrictions, usually prepended to the actual publication.

We will continually increase the number of publications on the full text server and add links here.
