Description:

It was a result of Greenlees and Sadofsky that classifying

spaces of finite groups satisfy a Morava K-theory version of Poincare

duality, which was proved by showing the contractibility of the

corresponding Tate spectrum. In this series of two talks, I will

explain the proof, discuss its generalization to quotient orbifolds and

consequences with examples. Some background in equivariant stable

homotopy theory will be given. If time permits, I will also explain why

the duality map can be viewed as coming from a Spanier-Whitehead type

construction for differentiable stacks.
