# Poster Exhibition 2011

The Bonn International Graduate School in Mathematics holds a poster exhibition of current Ph.D. projects each summer term. In the years 2002 to 2006 this was done jointly with the department of physics and astronomy. Since 2007 the poster exhibition is being organised by the Graduate School in Mathematics.

In the exhibition of July 7 and 8, 2011 members of the Graduate School in Mathematics presented their Ph.D. projects in the form of a poster in the entrance area, the Lipschitz-Hall and Plücker room of the Mathematics Center. All areas of mathematics were represented and the posters showed projects at all stages, from an early sketch to the almost finished thesis

BIGS hosted a party after the poster exhibition which lasted well into the evening. A good time was had by all, and we would like to thank all participants and helpers.
