Algebra Seminar

The seminar of the Algebra Research Unit is a combination of

Please write us if you want to be on our mailing list. (Or, as the case may be, if you want to be removed from the list.)

During the fall semester 2011 we usually meet on Fridays at 12:15 in the "small seminar room 104", which is in the green zone on the 5th floor of the "Freihaus Building" (Wiedner Hauptstrasse 8-10, 1040 Wien). Talks last between 45 and 90 minutes, and are given in German or English, depending on the audience and the speaker.

Note that Friday is also the day of the main colloquium of our institute (occasionally on the first Friday of every month). Occasionally we share topics and/our audiences with the National Research Network "Analytic Combinatorics and Probabilistic Number Theory".
