Publications

Publications are probably the most important indicator of successful
research activities -- although not the only one. They could be judged
in several ways, by quantity (sheer number of papers), by quality
(rating of the journal), by impact (number of citations obtained). None
of these figures provides an objective insight in the achievements of
the past five years. Because we started with a completely new research
agenda rather than continuing previous activities, it is obvious that
in early years the publications were quite sparse. It took some time
before the first results were obtained, and even longer before they
were developed towards a level that matches the quality standards of
top journals. On another note, interdisciplinary research cannot be
easily placed in major journals which sometimes have a quite narrow
focus. In this respect, we first had to adapt to the standards of
different scientific communities, ranging from economics and the social
sciences to computer science and statistical physics.

As the list of publications below demonstrates, there is a broad
spectrum of papers, mostly in reviewed journals and proceedings of
competitive conferences, which encompasses our diverse research topics.
The increasing number of publication shows that we are advancing in
most of these areas.
