Workshop Stable Homotopy Theory and Algebraic K-theory

Bielefeld/Germany, February 22-24, 1999

The workshop will be held at the Department of Mathematics of the University of Bielefeld . It is hosted and funded by the SFB 343 "Diskrete Strukturen in der Mathematik".

Registration: Formal registration is not required, but the organizers appreciate an email note from those who plan to attend, so that we get an idea of how many participants to expect.

All talks will take place in Lecture Hall 6 (`Hörsaal 6') which is located at the west end of the main hall inside the university building.
