Spring Semester 2004

Mathematics Colloquium


The Mathematics Colloquium takes place on Mondays at 17:15 in East Hall 4.
There will be tea starting at 16:45 in East Hall near the entrance to Room 4.
East Hall is essentially the last building on your left when you keep walking straight on from the IUB main entrance. The simplest way to get in is to press the switch with the wheelchair symbol on it. More detailed information on finding the way can be found here.

Talks are (or should be) directed at a general mathematical audience.
Everybody is encouraged to invite external speakers. Please use the table below to find out what dates are available and send me a line in order to reserve one.

We keep a Colloquium Book; each speaker is asked to write a handwritten abstract of the talk into it.
