Forschungsseminar Outer space and QFT

Summer Term 2016

Dr. Daniela Egas Santander  -  Prof. Dr. Dirk Kreimer   -  Prof. Dr. Holger Reich 

  • Time and place:   Thursday,  2 - 4 p.m.,   SR 055, Takustr. 9    

Outer space and QFT

This is a bi-weekly seminar on quantum field theories and their relation to topology in particular Outer space and other spaces of graphs. The talks will be given in tandem one mathematician - one physicist. One of the speakers is the "novice" i.e., the one belonging to a different field than the subject of the talk while the other speaker is the "expert". The idea is that the "expert” understands the big picture while the "novice" will help bring the presentation to a language more reachable by their home group.
