What is the subfactor planar algebra of type $\tilde{A}_n$, of index 4?
Kevin, can you tell me more about what $Z$-homology and $Z/n$ homology mean here? |

Flattening a corner in a convex $d$-polytope (into $d-1$ dimensions, without overlap)?
Igor, this "Archimedes axiom" seems like it would do the trick. On the other hand, Crofton's formula seems to be stated for the plane -- does a more general version exist for other surfaces (or just the sphere)? And do you know of proofs of the Archimedes axiom in higher dimensions? |

Flattening a corner in a convex $d$-polytope (into $d-1$ dimensions, without overlap)?
Allen -- thanks! This paper, in fact, proves much stronger results than the one I'm asking about. On the other hand, the tools it invokes go well beyond convex geometry, so I'm still curious about whether there's a simple proof of this fact. |

Where does a math person go to learn statistical mechanics?
That's great, I didn't realize it was online and free. Wish I could upvote it twice for that reason! |
