Publications
Here you find some of my recent scientific publications (as postscript files),
plus a few presentations for the public at a somewhat more popular style
(partly in German) at the bottom.
A
full list (sorted in time) is also available for those who are extremely
inquisitive, as well as a
CV (in German).
