Because of the attack on the computer network of the University of Duisburg-Essen, some content (in particular some image files) cannot be accessed because it is stored on central servers of the university.

The following list contains publications of members of the research group not co-authored by D. Greb. Information on publications (co-)authored by D. Greb can be found here.
