Proseminar on
Algebraic Topology and Category Theory
Spring 2009

Time and Place: Tuesdays and Thursdays 1:30-3:00 in Eckhart Room 203. Talks will be in the fields of
topology, category theory, and their intersection.

Audience: Graduate students in their second year or higher, with an interest in algebraic topology and/or category theory.
Postdocs and other faculty interested in these topics will also attend. Talks will be contributed by people at all levels.
