Research Seminar - Summer term 2016


Description:

This is the joint research seminar of the groups of Christoph Schweigert and Ingo Runkel. The seminar takes place
  • Tuesdays 14:15-15:45 in room 241
The plan for this term is (subject to change):
  • Tue, 5.4.: (no seminar)
  • Tue, 12.4.: Lorant Szegedy on area dependent 2d quantum field theory
