| Nov 9, 2017 at 6:43 | comment | added | Carl | @MarcoGolla Good point. I guess I would like the moves to be simple enough that the cobordism itself is obvious in some way, but that may just come from Rohklin's theorem, and that's enough to make me realize I'm probably asking the wrong question. | |
| Nov 9, 2017 at 6:29 | comment | added | Marco Golla | I don't have time to elaborate right now, but I think that the answer to 2) is yes, by using handle decompositions of 5-manifolds. 1) is not really well-posed, since one could just say "any move that preserves the signature will do". | |
