## Topology Seminar: Galois descent and pro objects

• Date: 07/21/2010
Lecturer(s):
Rick Jardine (University of Western Ontario)
Location:

University of British Columbia

Description:

A Galois descent theorem for n-types will be displayed and explained. This result is used, together with an appropriate version of the homotopy theory of pro objects, to give a descent criterion for diagrams of spaces which are defined on the etale site of a field. The need for such a criterion first arose in connection with the algebraic K-theory of fields.

Schedule:

3:00 - 4:00pm, WMAX 110.
