Fix broken links, add one more example

Aug 4, 2010 at 9:04 | comment | added | Ryan Budney | Again with this, there's infinitely many indecomposables. | |
Aug 4, 2010 at 9:03 | comment | added | Ryan Budney | Hyperbolic knots and links have further decompositions but I'm not aware of any that decompose them into knots and links. A classic and closely-related decomposition to the one above is sometimes called the "rational-tangle decomposition" or the "$\mathbb Z_2$-equivariant JSJ-decomposition." It is what you get when you look at the JSJ-decomposition of the $\mathbb Z_2$-branched cover of $S^3$, branched over the link. www-bcf.usc.edu/~fbonahon/Research/Preprints/BonSieb.pdf | |
Aug 4, 2010 at 7:59 | comment | added | Peter Samuelson | Ah, I should have looked at Wikipedia before commenting. It looks like there's much more information here arxiv4.library.cornell.edu/abs/math/0506523 :-) And it looks like the answer to the question in the comment above is no... | |
Aug 4, 2010 at 7:50 | comment | added | Ryan Budney | Hyperbolic knots and torus knots are precisely the indecomposables. There's infinitely many of both. | |
Aug 4, 2010 at 7:37 | comment | added | Peter Samuelson | These are very nice pictures, thanks! Are there finitely many knots that are "indecomposable" in this sense? | |
