WWU -- SFB 478
Geometric Structures in Mathematics  


Workshop on curvature and Global shape



  • June 22 - June 28 2009




Conference Schedule



Talks will be scheduled from Tuesday (June 23) till Saturday (June 27) with a party on Saturday evening and bicycle tour (32 km round trip) on Thursday afternoon. You can view the trace of the tour on GoogleEarth. Every invited participant who would like to talk is welcome to submit a suggestion. The talks do not need to relate to Detlef Gromoll's work. We have scheduled a special lecture on Detlef Gromoll's work by Karsten Grove for Wednesday evening (6 pm).

The talks will be given in lecture room M2 or M4 of the lecture hall building (building #1 on the local map).
