Cobordism of involutions revisited, revisited
arXiv:1106.5416
Abstract
This is an old talk about Boardman's work in Z/2-equivariant unoriented cobordism. It appeared long ago, but it discusses a useful geometric interpretation of Tate cohomology which doesn't seem to be widely known. I'm posting it in an attempt to advertise those ideas.
