Spaces with symmetry: orbifolds and equivariant homotopy
Abstract: The theory of orbifolds and that of equivariant homotopy both try to
understand spaces which have symmetry, and both fields often wind up describing
the same phenomena. Traditionally, however, the definitions and viewpoints of
the two approaches have been quite different. I will try to describe a little
bit of how each views the subject, and talk about making a closer connection
between them, allowing results from equivariant homotopy to be applied to
orbifolds. This is joint work with Dorette Pronk from Dalhousie.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
