Topology Date:  Thursday, March 14, 2013 Location:  3088 East Hall (3:00 PM to 4:00 PM) Title:  Ziwet Lecture III: Equivariant multiplicative closure Abstract:   The "multiplicative closure" of a set of elements in a commutative ring is the set of all products of powers of those elements. One of the innovations used in our solution to the Kervaire invariant problem revealed an unexpected subtlety in the analogue of this notion in equivariant homotopy theory. In this talk I will describe this analogy and explain the subtlety and the structures needed to deal with it.
