This page contains a list of all my publications to date (an alternative list can be obtained via my ORCiD account: ). For faster access, I have organised the list into the following groups:

Clicking on the title of a paper opens a page with additional information. Usually this includes a brief description of the content (or some other comments) and in most cases you can download a PDF version of the paper. For the older papers only Postscript files (compressed with gzip) are provided.

You can also download a postscript version of both my Ph.D. thesis and my habilitation thesis.
