Research seminar on graph theory (Winter Semester 2012/13)

This is an informal seminar in which we come together, give talks, share problems and discuss them. Everyone is welcome to join us, give a talk or just listen. The content covered by the talks includes but is not limited to:

  • presentation original research
  • report on conferences attended
  • presentation of interesting and relevant articles

If you want to give a talk, please contact Torsten Ueckerdt . You are very welcome!

How to find us

The seminar room K2 is within the building 01.93 located in Kronenplatz 32. You can find it on campus-sued-plan.pdf|this map in square D9. When standing on Kronenplatz look for a travel agency called "Reiseland" and for the entrance left of it. The door is usually locked but there is a door bell at the panel labeled KIT Mathematik Seminarraum. Ring that bell and wait for someone to open.


  • For now on the seminar will take place Tuesdays from 11:30am to 1:00pm!

Seminar: Tuesday 11:30-13:00 Begin: 9.10.2012
