   Format: MarkdownItexI woke this morning wondering whether there was something like [[Pontrjagin duality]] for abelian $\infty$-groups. Of course, as soon as you look into these things a whole world opens up. Now I know we need to have at least an entry for [[Brown-Comenetz duality]], but probably also a whole lot more.

   Format: MarkdownItexSo I started [[Brown-Comenetz duality]], but it could do with much more by someone who knows what it's good for. There also seems to be an interesting general account of duality in Dwyer et al.'s [Duality in Algebra and Topology](http://www.math.tamu.edu/~cwilkers/seminar-papers/Duality.pdf).
