| Dec 19, 2015 at 19:54 | comment | added | Qiaochu Yuan | @მამუკა ჯიბლაძე: the missing pieces are to 1) give this some meaning and 2) write down a transgression map that "integrates" such a thing over an elliptic curve (or algebraic curve of higher genus) to produce a line bundle. | |
| Dec 19, 2015 at 9:16 | comment | added | მამუკა ჯიბლაძე | So the only missing piece is to provide meaning of something like $Z^3(-,{\mathbb C}^\times)\sim Z^2(-,Pic)\sim Z^1(-,Br)$? Or there are some other unclear details? | |

| Dec 19, 2015 at 8:30 | comment | added | მამუკა ჯიბლაძე | So why is this not an answer? :D | |
