This is the Juvitop seminar webpage from Spring 2006, which was organized by Tyler Lawson about Stacks in Homotopy Theory and Topology. This site was originally hosted here. This is part of a deep copy of all prior Juvitop websites that I could find in the fall of 2016.

This semester, the Juvitop seminar is focusing on stacks in topology and homotopy theory.

Talks are on Wednesdays at 4:30pm in 2-143.
