Wintersemester 2007/2008
Forschungsseminar (seminar for PhD students)

• Date: usually on Tuesdays 10-12 am at the Institut für Experimentelle Mathematik.
• Starting date: 18th October 2007
• The language of the seminar will be English or German depending on the speaker and the audience.

Contents and Aims

Every participant is invited to grant the others insights into his/her ongoing or past research.

The aim of this seminar is to stipulate the exchange of ideas.

All talks

• should introduce the audience to the speaker's area of research,
• should explain and motivate the questions (to be) studied,
• can, but need not, contain original results.
