| Mar 22, 2017 at 23:01 | comment | added | AHusain | Let's form a chat to discuss separately. See on chat.stackexchange.com with title this question. | |
| Mar 20, 2017 at 9:29 | comment | added | Gorbz | Target does not necessarily need to be 3-fold. For M5 brane 6d (2,0) theory though I think it does. This is where upon proper constructions one can relate Nekrasov part. function on $\mathbb{R}^4$ and GW with target the 3fold with time direction remaining. I cannot find any reference for this story though. | |
| Mar 19, 2017 at 22:25 | comment | added | AHusain | No, need to be M-theory, just leave it as topological string. But I'm drawing distinction between string/M theories and ordinary field theories because of world/brane-sheet formalism. Also, yes forgot to make the target a 3-fold. | |
| Mar 19, 2017 at 12:45 | comment | added | Gorbz | Thanks, that is quite incorrect. $\Sigma$ for Donaldson has to be a 4 manifold while for GW (at least in the classical sense) has to be a 3fold. The connection should somehow arise from M-theory construction as $\mathbb{R} \times M_4 \times CY_3$. | |
| Mar 19, 2017 at 8:54 | comment | added | AHusain | At least physically, Donaldson is doing a 4d field theory with source $\Sigma$ while GW is doing a 2d field theory with target $\Sigma$. | |
