SFB Workshop 2014 "SFB Days"


Being half way through our first funding period, this workshop will give a unique opportunity to present our scientific work with the results achieved in the projects of the SFB/Transregio "Discretization in Geometry and Dynamics" and to intensify our exchange about it.The workshop is structured as a varied program of presentations, enabling deeper insight into the research work of your colleagues, as well as a framework of free time in which discussions and exchange can develop.

  • Date: 21.09. - 26.09.2014
  • Type: Workshop
  • Location: TU Berlin, Dept. of Mathematics, Strasse des 17. Juni 136, 10623 Berlin

Program 


Please find below the schedule for the „SFB-Days“. This workshop offers to all projects the opportunity to present their current state of research with their previous results.
The program lists all project numbers in their particular presentation time slots.

The length of the time slots is proportional to the number of auxiliary support staff in each project, resulting in ‚large’ and ‚regular’ slots.
‚Large’ projects get approx. 70 minutes presentation time plus additional discussion time (90 min slot). ‚Regular’ projects get approx. 40 minutes presentation time plus additional discussion time (45 min slot).
The projects are at liberty to structure their time slots as they find adequate.

Social Evening Information



Dear SFB Days participants! We've planned some activities on 25.09.2014. Our activity depends on the weather in Berlin. Due to this uncertainty we have planned two alternatives:

 

Warm and Dry:

Football and/or volleyball at 'Tempelhofer Feld' in front of the historical hangars.
After the sports, feel free to walk to the Bergmann-Kiez for drinks at one of the nice locations. 
 

Cold and Wet:

Watching a mathematical cinema film together at the TU Berlin. Talking, socializing, soft drinks and some snacks inside.
