15. G. Yu “Large scale geometry and its applications.”
The ideas of large scale geometry played an important role in geometry,
topology and group theory beginning with the works of Mostow, Margulis and
Gromov. Recently there have been a number of important developments in
this area. This article surveys these developments and their applications to
geometry and topology of manifolds.

helped us to organize this conference. We received generous ﬁnancial and logistical
support from the Hausdorﬀ Center for Mathematics in Bonn. Its staﬀ, especially
Anke Thiedemann and Laura Siklossy, provided an extensive help with the organi-
zation, and Heike Bacher and Kerstin Strehl-M¨uller handled the registration. The
assistants Batu G¨ uneysu, Benjamin Himpel, Carolina Neira Jim´ enez, and Boris
