This is old page. New page: Colloquium
The Department of Mathematical Sciences has a common colloquium which meets about once every three weeks with presentations of some current research topics by department faculty or visitors. Talks will assume only general mathematical background and all faculty and students are invited to participate
In connection to each colloquium, there is usually a short informal faculty gathering including announcements of the department chairman and others about current events. The meeting takes place either before or after the colloquium and will be announced separately
The Colloquium will normally take place on Mondays from 14:15 to 15:00 or 14:30 to 15:15 (depeding on the placement of the infoquarter) in room M203.

Instructions for contributors
Please bear in mind that the audience will include graduate students and researchers of quite different areas than your own. Therefore it would be greatly appreciated if the following aspects would be taken into account:
 Include a comprehensive account of the setting of the problems, where they come from and what the motivation for studying them is.
 Do not assume that the audience know all the definitions. Take sufficient time to allow the audience to grasp the stated definitions.
 It is better if everyone understands the main theorem than if 5 % understand the whole proof.
The saying has it that if you plan a talk for graduate students, then a few professors might understand it. Therefore we suggest that you plan your talk so that even undergraduates will understand it, and then maybe most of the audience will actually do so.
