This year's Nikolaus Conference at Lehrstuhl D für Mathematik was held
We had a series of short talks on representation and group theory, with an emphasis of computational aspects.
Everybody interested was invited to attend the meeting.
Look here to find a train connection to Aachen.
Once you are in Aachen you find Lehrstuhl D in the building Templergraben 64, 2nd floor. Here is a map of the city center.
